The Outer Space Treaty at a Glance

August 2017

Contacts: Daryl Kimball, Executive Director, (202) 463-8270 x107

The 1967 Outer Space Treaty bans the stationing of weapons of mass destruction (WMD) in outer space, prohibits military activities on celestial bodies, and details legally binding rules governing the peaceful exploration and use of space.

The treaty entered into force Oct. 10, 1967, and has 110 states-parties, with another 89 countries that have signed it but have not yet completed ratification.

Treaty Terms

The treaty forbids countries from deploying "nuclear weapons or any other kinds of weapons of mass destruction" in outer space. The term "weapons of mass destruction" is not defined, but it is commonly understood to include nuclear, chemical, and biological weapons. The treaty, however, does not prohibit the launching of ballistic missiles, which could be armed with WMD warheads, through space. The treaty repeatedly emphasizes that space is to be used for peaceful purposes, leading some analysts to conclude that the treaty could broadly be interpreted as prohibiting all types of weapons systems, not just WMD, in outer space.

The treaty's key arms control provisions are in Article IV. States-parties commit not to:

  • Place in orbit around the Earth or other celestial bodies any nuclear weapons or objects carrying WMD.
  • Install WMD on celestial bodies or station WMD in outer space in any other manner.
  • Establish military bases or installations, test "any type of weapons," or conduct military exercises on the moon and other celestial bodies.

Other treaty provisions underscore that space is no single country's domain and that all countries have a right to explore it. These provisions state that:

  • Space should be accessible to all countries and can be freely and scientifically investigated.
  • Space and celestial bodies are exempt from national claims of ownership.
  • Countries are to avoid contaminating and harming space or celestial bodies.
  • Countries exploring space are responsible and liable for any damage their activities may cause.
  • Space exploration is to be guided by "principles of cooperation and mutual assistance," such as obliging astronauts to provide aid to one another if needed.

Like other treaties, the Outer Space Treaty allows for amendments or member withdrawal. Article XV permits countries to propose amendments. An amendment can only enter into force if accepted by a majority of states-parties, and it will only be binding on those countries that approve the amendment. Article XVI states a country's withdrawal from the treaty will take effect a year after it has submitted a written notification of its intentions to the depositary states: the United States, Russia, and the United Kingdom.


Talks on preserving outer space for peaceful purposes began in the late 1950s at the United Nations. The United States and its Western allies submitted proposals in 1957 on reserving space exclusively for "peaceful and scientific purposes," but the Soviet Union rejected these efforts because it was preparing to launch the world's first satellite and test its first intercontinental ballistic missile.

In 1963, the UN General Assembly approved two resolutions on outer space that subsequently became the basis for the Outer Space Treaty. UN Resolution 1884 called on countries to refrain from stationing WMD in outer space. UN Resolution 1962 set out legal principles on outer space exploration, which stipulated that all countries have the right to freely explore and use space.

The United States and Soviet Union submitted separate draft outer space treaties to the UN General Assembly in June 1966. A mutually agreed treaty text was worked out over the next six months, and the UN General Assembly gave its approval of the treaty on December 19, 1966. The treaty opened for signature in Washington, Moscow, and London on January 27, 1967 and entered into force October 10, 1967.

Ukraine, Nuclear Weapons, and Security Assurances at a Glance

Contact: Kingston ReifDirector for Disarmament and Threat Reduction Policy, (202) 463-8270 x104

At the time of Ukraine’s independence from the Soviet Union in 1991, Ukraine held the third largest nuclear arsenal in the world, including an estimated 1,900 strategic warheads, 176 intercontinental ballistic missiles (ICBMs), and 44 strategic bombers. By 1996, Ukraine had returned all of its nuclear warheads to Russia in exchange for economic aid and security assurances, and in December 1994, Ukraine became a non-nuclear weapon state party to the 1968 nuclear Nonproliferation Treaty (NPT). The last strategic nuclear delivery vehicle in Ukraine was eliminated in 2001 under the 1991 Strategic Arms Reduction Treaty (START). It took years of political maneuvering and diplomatic work, starting with the Lisbon Protocol in 1992, to remove the weapons and nuclear infrastructure from Ukraine.

1990 Declaration of Sovereignty

Partly in an effort to gain international recognition, Ukraine’s pre-independence movement supported efforts to join the NPT as a non-nuclear weapon state. With its Declaration of Sovereignty on July 16, 1990, Ukraine pledged “not to accept, produce, or acquire nuclear weapons." However, despite this public commitment, Ukrainian politicians were not entirely united by the idea. Some felt that Russia was a still a threat and that they should keep the weapons as a deterrent.

1991 Minsk Agreement on Strategic Forces

With the dissolution of the Soviet Union, the Commonwealth of Independent States signed the Minsk Agreement on December 30, 1991, agreeing that the Russian government would be given charge of all nuclear armaments. However, as long as the weapons remained in Belarus, Ukraine, and Kazakhstan, the governments of those countries would have the right to veto their use. The target date for dismantling the weapons was set for the end of 1994.

1992 Lisbon Protocol

Ukraine signed the Lisbon Protocol on May 23, 1992. The protocol sought to return the nuclear weapons in Belarus, Kazakhstan, and Ukraine to Russia. All states were to join START and the NPT. However, within Ukraine, there was little motion towards the ratification of START, joining the NPT, or overall denuclearization. The protocol required that Ukraine adhere to the NPT as quickly as possible, but it gave the country up to seven years to follow through.

By late 1992, the Ukrainian parliament was vocalizing more pro-nuclear views. Some believed that Ukraine was entitled to at least temporary nuclear weapon status. Perhaps optimistically, the U.S. government promised Ukraine $175 million in dismantlement assistance. Instead, the Ukrainian government began implementing administrative management of the nuclear forces and claimed ownership of the warheads.

In late April 1993, 162 Ukrainian politicians signed a statement to add 13 preconditions for ratification of START, frustrating the ratification process. The preconditions required security assurances from Russia and the United States, foreign aid for dismantlement, and compensation for the nuclear material. Additionally, they stated that Ukraine would dismantle only 36 percent of its delivery vehicles and 42 percent of its warheads, leaving the rest under Ukrainian control. Russia and the United States criticized these demands, but Ukraine did not budge. In May 1993, the United States said that if Ukraine were to ratify START, Washington would provide more financial assistance. This began subsequent discussions between Ukraine, Russia, and the United States over the future of Ukrainian denuclearization.

1993 Massandra Accords

Ukrainian and Russian officials reached a set of agreements, including protocols on nuclear weapons dismantlement, procedure, and terms of compensation. However, the two sides could not agree on the final document, and the summit ultimately failed. 

1994 Trilateral Statement

The Massandra Accords set the stage for the ultimately successful trilateral talks. As the United States mediated between Russia and Ukraine, the three countries signed the Trilateral Statement on January 14, 1994. Ukraine committed to full disarmament, including strategic weapons, in exchange for economic support and security assurances from the United States and Russia. Ukraine agreed to transfer its nuclear warheads to Russia and accepted U.S. assistance in dismantling missiles, bombers, and nuclear infrastructure. Ukraine’s warheads would be dismantled in Russia, and Ukraine would receive compensation for the commercial value of the highly enriched uranium. Ukraine ratified START on February 3, 1994, repealing its earlier preconditions, but it would not accede to the NPT without further security assurances.

1994 Budapest Memorandum on Security Assurances

To solidify security commitments to Ukraine, the United States, Russia, and the United Kingdom signed the Budapest Memorandum on Security Assurances on December 5, 1994. A political agreement in accordance with the principles of the Helsinki Accords, the memorandum included security assurances against the threat or use of force against Ukraine’s territory or political independence. The countries promised to respect the sovereignty and existing borders of Ukraine. Parallel memorandums were signed for Belarus and Kazakhstan as well. In response, Ukraine officially acceded to the NPT as a non-nuclear weapon state on December 5, 1994. That move met the final condition for ratification of START, and on the same day, the five START states-parties exchange instruments of ratification, bringing the treaty into force.

2009 Joint Declaration by Russia and the United States

Russia and the United States released a joint statement in 2009 confirming that the security assurances made in the 1994 Budapest Memorandum would still be valid after START expired in 2009.

2014 Russian Annexation of Crimea

Following months of political unrest and the abrupt departure of Ukrainian President Viktor Yanukovych, Russian troops entered the Crimean peninsula of Ukraine in March 2014. On March 18, over the protests of the acting government in Kiev, the UN Security Council, and Western governments, Russia declared the annexation of Crimea. The United States, the United Kingdom, and Ukraine called the action a blatant violation of the security assurances in the 1994 Budapest Memorandum. However, according to the Russian Foreign Ministry, “the security assurances were given to the legitimate government of Ukraine but not to the forces that came to power following the coup d'etat.”

The Missile Technology Control Regime at a Glance

The Missile Technology Control Regime Guidelines and Annex

(Photo: Kirill Kudryavtsev/AFP/Getty Images)Established in April 1987, the voluntary Missile Technology Control Regime (MTCR) aims to limit the spread of ballistic missiles and other unmanned delivery systems that could be used for chemical, biological, and nuclear attacks. The regime urges its 35 members,1 which include most of the world's key missile manufacturers, to restrict their exports of missiles and related technologies capable of carrying a 500-kilogram payload at least 300 kilometers or delivering any type of weapon of mass destruction.2

Since its inception, the MTCR has been credited with slowing or stopping several missile programs by making it difficult for prospective buyers to get what they want or stigmatizing certain activities and programs. Argentina, Egypt, and Iraq abandoned their joint Condor II ballistic missile program. Brazil, South Africa, South Korea, and Taiwan also shelved or eliminated missile or space launch vehicle programs. Some Eastern European countries, such as Poland and the Czech Republic, destroyed their ballistic missiles, in part, to better their chances of joining the MTCR.3 The regime has further hampered Libyan and Syrian missile efforts.

Yet, the regime has its limitations. Iran, India, North Korea, and Pakistan continue to advance their missile programs. All four countries, with varying degrees of foreign assistance, have deployed medium-range ballistic missiles that can travel more than 1,000 kilometers and are exploring missiles with much greater ranges. India is testing missiles in the intercontinental range. These countries, which are not MTCR members except India, are also becoming sellers rather than simply buyers on the global arms market. North Korea, for example, is viewed as the primary source of ballistic missile proliferation in the world today. Iran has supplied missile production items to Syria.

How the MTCR Works

Each MTCR member is supposed to establish national export control policies for ballistic missiles, cruise missiles, unmanned aerial vehicles, space launch vehicles, drones, remotely piloted vehicles, sounding rockets, and underlying components and technologies that appear on the regime's Material and Technology Annex. Members can add items to or subtract them from the annex through consensus decisions.

The annex is divided into two separate groupings of items, Category I and Category II. Category I includes complete missiles and rockets, major sub-systems, and production facilities. Specialized materials, technologies, propellants, and sub-components for missiles and rockets comprise Category II.

Potential exports of Category I and II items are to be evaluated on a case-by-case basis. Approval for Category I exports is supposed to be rare. The regime's guidelines, which set out criteria for weighing possible exports, instruct members that "there will be a strong presumption to deny" Category I transfers. No exports of production facilities are to be authorized. MTCR restrictions for Category II exports are less severe, largely because many items in the category also have civilian uses. Members, however, are still asked to exercise caution in making such deals. No member can veto another's exports.

The MTCR identifies five factors that members should take into account when evaluating a possible export of controlled items:

  • Whether the intended recipient is pursuing or has ambitions for acquiring weapons of mass destruction;
  • The purposes and capabilities of the intended recipient's missile and space programs;
  • The potential contribution the proposed transfer could make to the intended recipient's development of delivery systems for weapons of mass destruction;
  • The credibility of the intended recipient's stated purpose for the purchase; and
  • Whether the potential transfer conflicts with any multilateral treaty.

MTCR members are asked to obtain an assurance from the intended recipient that it will only use the export for the purpose claimed when requesting the deal. Members are also to secure a pledge from the intended recipient that it will not transfer the requested item or any replicas or derivatives to a third party without permission.

Because the regime is voluntary and the decision to export is the sole responsibility of each member, the MTCR has no penalties for transfers of controlled items. However, U.S. law mandates that Washington sanction entities-individuals, companies, or governments (whether they are MTCR members or not)-exporting MTCR-controlled items to certain countries identified as proliferators or potential threats to U.S. security. Sanctions may also be levied if the United States judges the transfer contrary to the MTCR. Typically, Washington prohibits the charged entity from signing contracts, receiving aid, or buying arms from the U.S. government for a period of two years. Sometimes the penalties can be imposed for longer lengths of time or extended to commercial imports and exports as well.

Outside the MTCR

Several countries have pledged to abide by the MTCR without joining it. Israel, Romania, and the Slovak Republic have all committed to maintaining export controls consistent with the regime.

After several years of the U.S. curtailing its sale of missiles and missile technologies, China announced in November 2000 that it would not help other countries build ballistic missiles capable of delivering nuclear weapons. Beijing, which was a key contributor to Pakistan's missile development, and has in the past provided sensitive technology to countries like North Korea and Iran, also pledged that it would issue a comprehensive list of controlled items requiring government approval before export. That list, however, was not published until August 2002. In 2004, China applied for MTCR membership, and, at the time, voluntarily pledged to follow the regime's export control guidelines. Although China no longer sells complete missile systems and has tightened its export controls, its membership was rejected due to concerns that Chinese entities continued to provide sensitive technologies to countries developing ballistic missiles, such as North Korea.

In 2008 India voluntarily committed to following the MTCR export control guidelines, since that time the United States has been working to secure India's membership in the regime. India's announcement was made shortly before the Nuclear Suppliers Group granted an exemption to India. New Delhi continues to develop its own ballistic missile program. In June 2015, India formally applied for membership in the regime, but Italy blocked consensus on its application during the October 2015 plenary. Nine other countries applied as well in 2015, none of which were admitted into the regime. India was later admitted in June 2015. 

Hague Code of Conduct Against Ballistic Missile Proliferation

MTCR members spearheaded a voluntary November 2002 initiative, the Hague Code of Conduct Against Ballistic Missile Proliferation (formerly known as the International Code of Conduct Against Ballistic Missile Proliferation), calling on all countries to show greater restraint in their own development of ballistic missiles capable of delivering weapons of mass destruction and to reduce their existing missile arsenals if possible. The aim of the initiative is to establish a norm against missiles that could be armed with chemical, biological, or nuclear warheads. As part of the initiative, participating countries are to annually exchange information on their ballistic missile and space launch vehicle programs, as well as provide advance notice of any launches of ballistic missiles or space launch vehicles. The Hague Code of Conduct has 138 member states, including all MTCR members except Brazil. Brazil has expressed concerns about how the initiative might affect its space program.


1. MTCR members, followed by the year they joined the regime, are: Argentina (1993), Australia (1990), Austria (1991), Belgium (1990), Brazil (1995), Bulgaria (2004), Canada (1987), the Czech Republic (1998), Denmark (1990), Finland (1991), France (1987), Germany (1987), Greece (1992), Hungary (1993), Iceland (1993), India (2015), Ireland (1992), Italy (1987), Japan (1987), Luxembourg (1990), the Netherlands (1990), New Zealand (1991), Norway (1990), Poland (1998), Portugal (1992), Russia (1995), South Africa (1995), South Korea (2001) Spain (1990), Sweden (1991), Switzerland (1992), Turkey (1997), Ukraine (1998), the United Kingdom (1987), and the United States (1987).

2. Originally, the MTCR was limited to stopping the proliferation of nuclear-capable missiles, which was defined as a missile able to travel at least 300 kilometers with a 500-kilogram payload. Five hundred kilograms was considered the minimum weight of a first generation nuclear warhead, while 300 kilometers was believed to be the minimum distance needed to carry out a strategic strike. Members agreed in the summer of 1992 to expand the regime's objective to also apply to missiles and related technologies designed for chemical and biological weapons. That change took effect in January 1993. The move effectively tasked members with a making a more difficult and subjective assessment about an importer's intentions, as opposed to denying a specific capability (a missile able to deliver a 500-kilogram payload at least 300 kilometers), because many more missiles and unmanned delivery vehicles could be adapted to deliver lighter chemical and biological weapons payloads.

3. Prospective MTCR members must win consensus approval from existing members. U.S. policy is that new members that are not recognized nuclear-weapon states must eliminate or forgo ballistic missiles able to deliver a 500-kilogram payload at least 300 kilometers. The United States, however, made an exception in 1998 for Ukraine, permitting it to retain Scud missiles. Three years later, Washington also agreed to let South Korea develop missiles with ranges up to 300 kilometers to secure its membership in the MTCR. Seoul previously agreed in 1979 to limit its missile development to those with ranges less than 180 kilometers. South Korea was granted another extension in October 2012. Seoul and Washington reached an agreement allowing South Korea to extend the range of its ballistic missiles to 800 kilometers with a 500 kilogram payload. This extension will allow Seoul to target all of North Korea. South Korea tested a ballistic missile with a range of 500 km in June 2015 and announced in October 2015 that it would deploy systems with an 800 km range in 2017.

START I at a Glance

February 2019

Contacts: Daryl Kimball, Executive Director, (202) 463-8270 x107

Strategic Arms Reduction Treaty (START) I was signed July 31, 1991, by the United States and the Soviet Union. Five months later, the Soviet Union dissolved, leaving four independent states in possession of strategic nuclear weapons: Russia, Belarus, Ukraine, and Kazakhstan. On May 23, 1992, the United States and the four nuclear-capable successor states to the Soviet Union signed the Lisbon Protocol, which made all five nations party to the START I agreement. START I entered into force Dec. 5, 1994, when the five treaty parties exchanged instruments of ratification in Budapest. All treaty parties met the agreement's Dec. 5, 2001 implementation deadline. START I expired on Dec. 5, 2009.

On 31 July 1991, the US President, George Bush (sitting on the left), and General Secretary of the Communist Party of the Soviet Union, Mikhail Gorbachev (sitting on the right), sign the START I Agreement for the mutual elimination of the two countries’ strategic nuclear weapons. (Photo: Susan Biddle/Bush Library)Basic Terms:

  • 1,600 deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy (long-range) bombers for each side.
  • 6,000 "accountable" warheads on ICBMs, SLBMs, and heavy bombers, of which no more than 4,900 may be on ICBMs and SLBMs, 1,540 on heavy missiles (the Soviet SS-18), and 1,100 on mobile ICBMs (RSM-12M Topol).
  • Ballistic missile throw-weight (lifting power) is limited to 3,600 metric tons on each side.

Counting Rules:

  • Heavy bombers equipped only with bombs or short-range attack missiles (SRAMs) are counted as carrying one warhead each.
  • U.S. heavy bombers may carry no more than 20 long-range air-launched cruise missiles (ALCMs) each. The first 150 of these bombers count as carrying only 10 ALCMs each.
  • Soviet heavy bombers may carry no more than 16 ALCMs each. The first 180 of these bombers count as carrying only eight ALCMs each.
  • No more than 1,250 warheads may be "downloaded" (removed from) and not counted on existing multiple-warhead ballistic missiles.

Other Provisions:

  • START I ran for 15 years with an option to extend for successive five-year periods. Based on commitments made at the March 1997 Helsinki Summit, the sides agreed in principle to negotiate an agreement making the START treaties unlimited in duration.
  • Separate "politically binding" agreements limit each side to 880 sea-launched cruise missiles with ranges above 600 kilometers and the Soviet Backfire bomber to 500 kilometers.

IAEA Investigations of Iran's Nuclear Activities

October 2020

Contact: Kelsey Davenport, Director for Nonproliferation Policy, (202) 463-8270 x102

The International Atomic Energy Agency (IAEA) first publicly outlined its concerns about Iranian activities related to the development of a nuclear weapon in an annex to its November 2011 quarterly report on Iran's nuclear program. The report laid out 12 main areas for investigation, explained in detail below. These issues became known as the possible military dimensions, or PMDs, of Iran’s nuclear program. The IAEA’s concerns about these activities pre-dated the public report, and little progress was made to resolve these issues until 2013.

In November 2013, Iran and the IAEA announced a Joint Framework for Cooperation in which Iran agreed to take several steps to address the IAEA’s concerns, including providing information and access to research reactors and production plants. The IAEA and Iran agreed to additional steps in 2014.

Before Iran completed all of the steps, the 2013 Framework for Cooperation was superseded by the 2015 Roadmap for the Clarification of Past and Present Outstanding Issues regarding Iran’s Nuclear Program, which required Iran to provide information on all the concerns the IAEA had identified in the 2011 report.

The 2015 Roadmap was announced concurrently with the nuclear deal concluded between Iran and the P5+1 (China, France, Germany, Russia, the United Kingdom, and the United States). Sanctions relief in the nuclear deal was contingent upon Iran cooperating with the agency’s investigation. The IAEA released its assessment to conclude the Roadmap process in December 2015.

Beginning in 2019, the IAEA requested Iran answer questions about possible undeclared nuclear activities and materials. As part of that investigation, the IAEA requested that Iran allow inspectors access to facilities outside of the country’s declared nuclear program in order to follow up on evidence of undeclared nuclear materials and activities that, based on IAEA reports, appear likely to have been part of the pre-2003 weapons program. The IAEA and Iran signed an agreement on accessing two locations in August 2020, after prolonged negotiations and an IAEA Board of Governors Resolution in June 2020 calling upon Tehran to work with the agency.

2011 IAEA Report:

In November 2011, the IAEA released a report outlining the agency’s evidence that Iran had engaged in various activities related to nuclear weapons development. The report provided evidence suggesting that Iran pursued a structured nuclear program before the fall of 2003, and that certain weapons-related activities continued after that program was dismantled.

According to the report, Iran engaged in efforts to procure nuclear and dual-use materials and equipment. The twelve PMDs of Iran’s nuclear program detailed in the report are as follows: 1) Iran’s nuclear program management structure, 2) procurement activities, 3) nuclear material acquisition, 4) possession of nuclear components for an explosive device, 5) detonator development, 6) high explosives and associated experiments, 7) hydrodynamic experiments, 8) relevant modeling and calculations, 9) development of a neutron initiator, 10) preparations to conduct a nuclear explosive test, 11) integration of a nuclear warhead into a missile, and 12) studies looking into a prototype Iranian re-entry vehicle

Additionally, Iran was found to have acquired nuclear weapons development information and documentation from an unnamed clandestine nuclear supply network and to have explored development of an indigenously-designed nuclear weapon. The IAEA’s published November 2011 report omits details about the latter two points, but the nuclear supply network is widely believed to have been that of Pakistani physicist A.Q. Khan.

The report, consistent with a 2007 U.S. intelligence assessment, speculates that Iran’s structured nuclear program (known as the AMAD Plan) “was stopped rather abruptly pursuant to a ‘halt order’ instruction issued in late 2003 by senior Iranian officials,” and that certain research and development activities may have resumed. For more on the IAEA’s November 2011 report, see: The IAEA’s Iran Report: Assessment and Implications.

The agency’s 35-member Board of Governors adopted a resolution Nov. 18, 2011, that expressed “deep and increasing concern about the unresolved issues regarding the Iranian nuclear program” and called on Iran to provide the agency with “access to all relevant information, documentation, sites, material, and personnel.”

Iran’s senior nuclear negotiator Saeed Jalili responded positively to a call from China, Russia, France, Germany, the United Kingdom and the United States (P5+1) to begin negotiations on Iran’s nuclear program in February 2012. Iran and the P5+1 met in April of that year.

2013 Joint Statement on Framework for Cooperation

Prior to reaching the July 2015 roadmap, the IAEA and Iran had taken some steps to clarify the outstanding issues between 2013-2014. 

Under the November 11, 2013 Framework for Cooperation, Iran and the IAEA committed to resolving the agency's concerns through a step-by-step process to address all of the outstanding issues. An annex to the framework laid out the first six actions that Iran pledged to take within three months (see details below).

On February 9, 2014, Iran and the IAEA announced a further seven actions that Iran would take by May 15, 2014 (see details below). Iran completed the initial two sets of actions within the time period specified, all of which fall into one of the 12 main areas of investigation. In June 2014, IAEA Director General Yukiya Amano said that the agency would not issue an assessment on any action until the investigation was completed and the agency could assess the information gathered as a system.

A May 20, 2014 meeting resulted in an agreement on an additional 5 actions to be taken by August 25, 2014 (see details below). Iran completed three of the five actions by the end of August 2014. Two remaining issues related to nuclear weapons development remained unresolved. Iran and the IAEA met several times throughout the spring, and in its May 29, 2015, quarterly report, the IAEA noted that Iran shared information on one of the outstanding issues related to nuclear weapons development. Before all of these actions were completed, this agreement was superseded by the July 2015 Roadmap. 

The full text of the initial Framework for Cooperation and its accompanying annex is available here. The detailed steps taken under the original framework are laid out below.

2015 Roadmap for the Clarification of Past and Present Outstanding Issues Regarding Iran’s Nuclear Program

The July 14, 2015, Roadmap laid out a schedule for Iran to address the IAEA’s concerns and the agency to complete its investigation.

The IAEA announced on August 15, 2015, that Iran met the first deadline for providing documents and written explanations to the agency's questions regarding the 12 main areas for investigation as outlined in the November 2011 annex. The agency submitted follow-up questions to Iran on September 9, and on September 20, IAEA Director General Yukiya Amano and Deputy Director General Tero Varjoranta traveled to Tehran to discuss the investigation and visit the Parchin site. They confirmed that environmental samples were taken at Parchin for analysis in IAEA labs. On October 15, 2015, the deadline for additional responses, the IAEA confirmed that Iran had responded to its follow-up questions and completed all activities under the roadmap.

The completed assessment, released on December 2, 2015, concluded that Iran had pursued a nuclear weapons program prior to 2003, including a coordinated “range of activities relevant to the development of a nuclear explosive device,” but did not divert nuclear material from its civilian nuclear program as part of its weaponization efforts.

The report found that although Tehran’s organized nuclear weapons program ended in 2003, some activities continued through 2009. According to the assessment, the “activities did not advance beyond feasibility and scientific studies, and the acquisition of certain relevant technical competencies and capabilities.” The agency said it found “no credible indications” that nuclear material was diverted to the weapons program or that any undeclared activities have taken place since 2009.

In several areas, like nuclear testing preparations and fuzing, arming, and firing a payload, the IAEA did not receive any new information. In other areas, such as Iran’s work at a uranium mine, the IAEA assessed that Tehran’s activities were consistent with its declaration to the IAEA. However, the IAEA assessed that Iran’s program structure, computer modeling of a nuclear explosive device, and certain types of experiments with detonators were part of a nuclear weapons development program prior to 2003.

Mark Toner, a deputy spokesman at the U.S. Department of State, said on December 2 that the IAEA’s conclusion is “consistent with what the United States has long assessed with high confidence.”

Following a meeting on December 15, 2015, the 35-member IAEA Board of Governors voted unanimously to close the investigation into Iran's past weaponization work while continuing to report on Iran's implementation of the July 2015 nuclear deal with the P5+1.

Iran's ambassador to the IAEA Reza Najafi said that Iran "disagreed" with some of the agency's findings, arguing that the “scientific studies of dual-use technologies have always been for peaceful civilian or conventional military uses” rather than nuclear weapons work, he said.

The full text of the "road-map for the clarification of past and present outstanding issues regarding Iran’s nuclear program" is available here. Highlights of the IAEA's findings in each of the 12 areas are below:

  1. Program management structure: The IAEA assessed that, prior to 2003, Iran had an organized structure “suitable for the coordination of a range of activities relevant” to nuclear weapons design. The activities that continued beyond 2003 were not a coordinated program.
  2. Procurement activities: The IAEA had “indications” that Tehran attempted to purchase items relevant to developing a nuclear weapon prior to 2007 and information that Iran purchased materials for its fuel cycle activities through companies not affiliated with the Atomic Energy Organization of Iran. Iran admitted to looking into procuring a high-speed camera for conventional purposes but said it ultimately did not do so.
  3. Nuclear material acquisition: The IAEA assessed that the Gchine uranium mine, previously thought to be a potential source of uranium for undeclared nuclear activities between 2000-2003, would not have produced any substantial amounts of nuclear material before 2006. The IAEA found that the activities at the mine were consistent with Iran’s explanations and declarations. Overall, the IAEA assessed that “any quantity of nuclear material” that would have been available for the nuclear weapons development program “would have been within the uncertainties associated with nuclear material accountancy and related measurements.”
  4. Nuclear components for an explosive device: The IAEA had evidence that Tehran had access to documentation on the conversion of uranium compounds to uranium metal, which is part of the weaponization process, and made progress on reducing a uranium compound into a metal form. Tehran denied that it conducted any metallurgical work for weapons purposes. The IAEA’s final assessment found no indication of Iran conducting activities related to the uranium metal document.
  5. Detonator development: The IAEA assessed that Iran’s work on explosive bridge wire detonators has “characteristics relevant to a nuclear explosive device.” The agency found that some of Iran’s explanations, that the detonators were developed as a safer alternative because of explosive accidents, were “inconsistent” and “unrelated” to the IAEA’s timeframe for detonator development.
  6. Initiation of high explosives and associated experiments: Iran admitted to the IAEA in August and September 2015 that it conducted work on certain types of explosives, but had a “technical requirement for the development” of multipoint initiation explosive technology for conventional weaponry. The IAEA noted that there are non-nuclear weapons applications for the development, but assessed that the work was “relevant to a nuclear explosive device.”
  7. Hydrodynamic experiments: As part of its investigation over the past several months, IAEA officials were able to visit Parchin, a military site where the agency suspected that Tehran conducted hydrodynamic tests in an explosive chamber. Since the IAEA requested access in 2012, Iran conducted extensive construction and renovations. Tehran said in September 2015 discussions with the IAEA that one of the main buildings in question was used for storing chemicals for the production of explosives. An environmental sampling at the site found “chemically man-made particles of uranium” but did not indicate that it was used for long-term storage of chemicals as Iran claimed. The IAEA assessed that its satellite imagery analysis and environmental sampling “does not support Iran’s statements on the purpose of the building” and that Iran’s activities at the site impeded the agency’s investigation. The IAEA did not draw a definite assessment as to what occurred at Parchin.
  8. Modeling and calculations: The IAEA assessed that Iran conducted modeling and calculations related to nuclear explosive configurations prior to 2004 and between 2005-2009. During the agency’s investigation between August-October 2015, Iran maintained that it was not in a position to discuss its work on hydrodynamic modeling because it was for conventional military purposes and not an IAEA concern. The IAEA noted in its report that there are conventional applications for such modeling and that the calculations derived from the modeling were incomplete and fragmented, but assessed overall that Iran conducted computer modeling of a nuclear explosive device between 2005-2009.
  9. Neutron initiator: The IAEA’s evidence indicated that Iran continued work on neutron initiators after 2004, although the agency assessed prior to the July 2015 agreement with Iran that some of the indicators that Iran undertook work on generating neutrons through shock-compression were “weaker than previously considered.” Iran provided the IAEA with information about its neutron research and let the IAEA visit a research intuition in October 2015. Iran maintained that its research in the area was not related to “shock-driven neutron sources.”
  10. Conducting a test: The IAEA noted it has not received any additional information regarding Tehran's plans to conduct a nuclear test since its November 2011 report. The IAEA noted in the November 2011 report that Iran may have undertaken “preparatory experimentation” relevant to a nuclear weapons explosive device and obtained a document on the safety arrangements for explosive nuclear testing.
  11. Integration into a missile delivery vehicle: The IAEA assessed that two of the workshops it identified in 2011 as producing components and mock-up parts for engineering of a Shahab-3 (Iran’s medium-range ballistic missile) re-entry vehicle for a nuclear warhead exist and that the capabilities are “consistent with those described” in documentation provided to the agency on Tehran’s work on a re-entry vehicle.
  12. Fuzing, arming, and firing system: The IAEA report noted in the Final Assessment report that it had not received any new information since the November 2011 report on development of a prototype firing system for a Shahab-3 payload that would allow the missile’s payload to safely re-enter the atmosphere and then explode above a target or upon impact.

2019 Investigation

While the PMD investigation was closed in 2015, the IAEA is mandated to ensure that all nuclear materials and activities in Iran are under appropriate safeguards. The IAEA is obligated to investigate if it has evidence of undeclared nuclear materials and activities and press Iran for information or access as inquiries regarding its safeguards implementation arise.

In 2018, Israeli Prime Minister Benjamin Netanyahu said that Israel provided the IAEA with copy of documents that Israel stole from Iran. The documents, known as the “Atomic Archive” allegedly contained information about Tehran’s nuclear weapons activities. Based on the information, Netanyahu pressed the IAEA to investigate a warehouse in the Turkazabad district of Iran.

The IAEA has not publicly confirmed receipt of the archival material or whether the documents are the basis of the agency’s requests to Iran for information and access that began in 2019. IAEA officials have also reiterated that any information provided by member states is subject to the agency’s review and verification process. According to former U.S. Under Secretary of State for Arms Control and International Security Andrea Thompson, the IAEA has worked to unpack and clarify a mountain of information about Iran’s possible past nuclear activities revealed in the so-called ‘atomic archive’ since Netanyahu first commented on the archive in 2018.

In November 2019, Acting-Director General Cornel Feruta told a special convening of the Agency’s Board of Governors that the IAEA had “detected natural uranium particles of anthropogenic origin at a location in Iran not declared to the Agency.” It was later speculated that that location was the Turquzabad site, which IAEA inspectors had visited earlier that year to take environmental samples.

Seeking to explain the presence of undeclared uranium, Iranian officials have stated that the warehouse was previously owned by a private company that may have used the facility to store equipment from Iran’s uranium mine. According to the spokesman of the Atomic Energy Organization of Iran, “particles can fly and land anywhere.”

In March 2020, the IAEA released a report detailing additional efforts by the Agency over the past year to investigate three sites in Iran associated with possible undeclared nuclear activities and the storage of nuclear materials. The locations and activities in question were again presumed related to Iran’s pre-2004 nuclear weapons research. The reported noted that the IAEA requested access to two of the sites in January 2020, but Iran had refused to allow inspectors to visit the areas in question. Diplomats have alluded to the fact that the Agency’s investigation into these three sites is connected to its investigation into the atomic archive, suggesting the two may be closely related.

Iran refused to cooperate with the Agency’s requests for over a year, until August 2020, when Tehran and the IAEA settled their dispute after Iran agreed to grant the Agency access to two of the sites to conduct environmental sampling. It was reported Sept. 30 that the IAEA completed its inspection of the second site, and that environmental samples from both locations were sent to agency labs to test for the presence of nuclear material.

Nuclear-Weapon-Free Zones (NWFZ) At a Glance

July 2017

Press Contacts: Kelsey Davenport, Director for Nonproliferation Policy, (202) 463-8270 x102


What is a Nuclear-Weapon-Free Zone?

A nuclear-weapon-free zone (NWFZ) is a specified region in which countries commit themselves not to manufacture, acquire, test, or possess nuclear weapons. Five such zones exist today, with four of them spanning the entire Southern Hemisphere. The regions currently covered under NWFZ agreements include: Latin America (the 1967 Treaty of Tlatelolco), the South Pacific (the 1985 Treaty of Rarotonga), Southeast Asia (the 1995 Treaty of Bangkok) Africa (the 1996 Treaty of Pelindaba) and Central Asia (the 2006 Treaty of Semipalatinsk).


Initial efforts to create an area free of nuclear weapons began in the late 1950s with several proposals to establish such a zone in Central and Eastern Europe. Poland offered the first proposal-named the Rapacki Plan after the Polish foreign minister-in 1958. The Rapacki Plan sought to initially keep nuclear weapons from being deployed in Poland, Czechoslovakia, West Germany, and East Germany, while reserving the right for other European countries to follow suit. The Soviet Union, Sweden, Finland, Romania, and Bulgaria also floated similar proposals. All these early efforts, however, floundered amidst the U.S.-Soviet superpower conflict, although the Rapacki Plan would serve as a model to the nuclear-weapon-free zones that were eventually set up in other regions of the globe.

Article VII of the nuclear Nonproliferation Treaty (NPT), which entered into force in 1970, affirms the right of countries to establish specified zones free of nuclear weapons. The UN General Assembly reaffirmed that right in 1975 and outlined the criteria for such zones. Within these nuclear-weapon-free zones, countries may use nuclear energy for peaceful purposes.

Protocol for Nuclear Weapon States

Each treaty establishing a nuclear-weapon-free zone includes a protocol for the five nuclear-weapon states recognized under the NPT-China, France, Russia, the United Kingdom, and the United States-to sign and ratify. These protocols, which are legally binding, call upon the nuclear-weapon states to respect the status of the zones and not to use or threaten to use nuclear weapons against treaty states-parties. Such declarations of non-use of nuclear weapons are referred to as negative security assurances. For more information, see Nuclear Declaratory Policy and Negative Security Assurances.

However, the five nuclear-armed countries have at times signed and ratified a NWFZ protocol and declared conditions reserving the right to use nuclear weapons in certain scenarios against parties to a nuclear-weapon-free zone. For instance, the United States signed the protocol for the African nuclear-weapon-free zone in April 1996 with a declaration that it would reserve the right to respond with all options, implying possible use of nuclear weapons, to a chemical or biological weapons attack by a member of the zone. None of the nuclear-weapon states have signed the relevant protocol for the treaty creating a zone in Southeast Asia because of concerns that it conflicts with the right of their ships and aircraft to have freedom of movement in international waters and airspace and problems with the definitions of territory, since includes exclusive economic zones and continental shelves. The other three zones do not explicitly rule out the transit of nuclear weapons by nuclear-weapon states through the zones, and the general practice of nuclear-weapon states is not to declare whether nuclear weapons are aboard their vessels.

In addition to nuclear-weapon-free zones, there are treaties and declarations, which are not covered by this fact sheet, banning the deployment of nuclear weapons in Antarctica, Mongolia, on the seabed, and in outer space.

Basic Elements of Nuclear-Weapon-Free Zone Treaties

Duration: The treaties are to remain in force indefinitely. Yet, each treaty includes a withdrawal option for states-parties. With the exception of the Treaty of Tlatelolco, which simply requires three months' advance notice before a withdrawal can take effect, all the NWFZ treaties require 12 months' advance notice for a state-party to end its treaty obligations.

Conditions: None of the treaties can be subjected to conditions by its non-nuclear-weapon states-parties.

Verification: Each state-party adopts comprehensive safeguards administered by the International Atomic Energy Agency (IAEA), which verifies that states-parties are not pursuing nuclear weapons illicitly. The Central Asian NWFZ goes a step further in requiring that states in the region adopt the IAEA's Additional Protocol, which provides for expanded monitoring.

Territory Covered: Each zone applies to the entire territories of all of its states-parties. Territory is understood to include all land holdings, internal waters, territorial seas, and archipelagic waters. The Latin American treaty also extends hundreds of kilometers from the states-parties' territories into the Pacific and Atlantic Oceans, but the nuclear-weapon states, citing their freedom at sea, assert that this does not apply to their ships and aircraft that might be carrying nuclear weapons. A dispute also exists over the inclusion of the Chagos Archipelago, which includes the U.S. military base at Diego Garcia in the Indian Ocean, as part of the proposed African nuclear-weapon-free zone. Neither the United States nor the United Kingdom recognizes Diego Garcia as being subject to the Pelindaba Treaty.

Arms Control and Proliferation Profile: China

July 2017

China, one of the five nuclear weapons states under the NPT, is estimated, as of June 2019, to possess 290 nuclear warheads, an arsenal that has steadily increased in recent years. It has simultaneously sought to modernize and expand its nuclear delivery systems, which include some 143 nuclear-capable land-based missiles and a limited number of submarines, SLBMs, and strategic bombers. China’s self stated nuclear policy has been to keep its capabilities at the minimum level required to maintain its national security and to deter a potential first strike, and it was the first nation to declare a “No First Use” policy.

Nuclear Weapons Programs, Policies, and Practices

The Nuclear Arsenal, an Overview
China does not publicly release information about the size of its nuclear arsenal. As of June 2019, China is estimated to possess 290 warheads. China’s nuclear arsenal has been steadily increasing with respective figures placed at 240 in 2011 and 250 in 2013 and 260 in 2016 and 280 in 2018.  China’s warheads are thought to be kept in storage under central control during times of peace. It is uncertain whether or not China possesses a non-strategic nuclear arsenal.

China's nuclear policy has been defined by possessing the minimum capabilities needed to deter a first strike from a potential aggressor.

Delivery Systems
Nuclear Modernization

  • China’s nuclear delivery systems are undergoing modernization programs, keeping with the modernization efforts of its People’s Liberation Army (PLA). Such efforts are viewed by Chinese leaders as essential for achieving great power status and advancing national interests and sovereign claims.
  • Hans M. Kristensen & Robert S. Norris report that, “The modernized force is more mobile, responsive, and accurate, and can overwhelm a limited US ballistic missile defense system." 
  • According to the U.S. Department of Defense (DOD), China continues to field new and more advanced nuclear delivery systems with improved range and destructive capability.
  • China’s decision to switch some of its missiles from liquid to solid fuel has improved their capabilities, in both range and promptness of launch. 

 Intercontinental Ballistic Missiles (ICBM)

  • China appears to maintain a minimal force of nuclear-armed ICBMs to ensure Beijing’s ability to execute a second strike.
  • Estimates place China as having around 143 nuclear-capable land-based missiles capable of delivering approximately 163 warheads. A 2016 Bulletin of the Atomic Scientists report estimates that around 50-75 of these land-based missiles are ICBMs, whereas the DOD’s annual military power report on China in 2017 figures China's ICBM arsenal at around 75-100 ICBMs. Only 40-50 of China’s ICBMs are capable of targeting the continental United States. 
  • China’s ICBM arsenal contains:
    • DF-4 (CSS-3): 5,500+ km range. 
    • DF-5A (CSS-4, Mod 2): 13,000+ km range.
    • DF-5B (CSS-4, Mod 3): ~12,000 km range. The DF-5B is a variant of the DF-5A upgraded to carry MIRVs.
    • DF-5C: on Jan. 31 2017, it was reported that China had flight tested the DF-5C, fixed with 10 warheads—a breakthrough in China’s nuclear weapons development. However, some experts are skeptical of this claim. The DF-5C is reported to be a two-stage, liquid-fueled missile with a range of around 8,000 miles (approximately 13,000 km).
    • DF-31 (CSS-10, Mod 1): 7,000+ km range.
    • DF-31A (CSS-10 Mod 2): 11,000+ km range.
    • DF-41: in development; flight-tested in 2016 with two MIRVs. It is a three-stage, solid propellant missile with an estimated range of 12,000-15,000 km and is believed to be able to carry up to ten warheads. The DF-41 is intended to replace the older liquid-fueled DF-5As.
  • China is in the process of replacing the older liquid-fueled missiles such as the DF-4 and DF-5A with the solid-fueled ICBMs.
  • In January 2017, the DF-41, never publically displayed before, was alleged to have been deployed at the Russian border, although many experts believe it has not completed development. 
  • China’s land-based missiles, both conventional and nuclear, are under the control of the PLA Rocket Force, a command of 100,000 personnel.

Submarines and Submarine-Launched Ballistic Missile (SLBM)

  • As of March 2017, China has a fleet of 4 Jin-class (Type 094) nuclear-powered ballistic missile submarines (SSBNs). The Jin-class SSBNs are designed to carry the new JL-2 SLBMs.
  • An additional 4 Jin-class SSBNs have been commissioned and at least one is under construction.
  • China possesses two SLBM types:
    • JL-1 (CSS-NX-3): estimated range of 1,000+ km. JL-1 missiles are being replaced by JL-2s.
    • JL-2 (CSS-NX-14): a modified version of the DF-31 ICBM; estimated range of 7,000+ km but some estimates place the number at 8,000-9,000 km.
  • Five Jin-class submarines may enter service before China begins developing and fielding its next-generation SSBN, the Type 096, over the coming decade. The type 096 submarine is expected to carry both the JL-2 and a new missile, the JL-3, which is to be the JL-2’s anticipated successor.
  • Despite various claims to the contrary, it is unclear whether or not Chinese submarines have undergone any deterrent patrols. Beginning in early 2015, it was reported that a Chinese SSBN has undergone a 95-day patrol. 

Strategic Bombers

  • China has begun to update its outdated nuclear-capable bomber fleet.
  • According to a DOD report, China continued, in 2015, to develop long-range bombers, including some that Chinese military analysts have described as “capable of performing strategic deterrence.”
  • The PLA air force was assigned a “strategic deterrence” mission in 2012.
  • As of December 2016, China’s fleet of nuclear-capable bombers consisted of about 20 Hong-6 (H-6) bombers based on Soviet designs, with a range of only 3,100+ km.  
  • The H-6 bombers are only capable of delivering an unspecified number of gravity-based bombs but are not believed to be assigned an active nuclear mission.
  • Media reports suggest that China may develop a new nuclear bomber capability in the future.
  • The PLA Air Force operates a fully redesigned H-6 variant known as the H-6k that has an extended range and is capable of carrying six land attack cruise missiles.
  • In March 2017 it was announced that the 5th generation Chengdu J-20 stealth fighter jet had entered into service, putting China one step closer to rivaling U.S. air superiority in East Asia.  

Fissile Material

  • Although China has not publicly declared a halt to the production of fissile material for weapons purposes, highly enriched uranium (HEU) and separated plutonium, general speculation is that Beijing has stopped its production. China is reported to have last produced HEU in 1989 and last produced separated plutonium in 1991.
  • The International Panel on Fissile Material's 2015 report estimates that China maintains a stockpile of 18 ± 4 metric tons of military HEU and 1.8 ± 0.5 metric tons of weapon-grade plutonium. At the present, the limited size of China’s military stockpile restricts its ability to produce more warheads.
  • China has not declared a civilian HEU stockpile and, as of 2016, maintains an estimated civilian plutonium stockpile of only 25.6 kg.

Proliferation Record

  • China has a record of assisting states with nuclear and missile programs in the past, but in 2000, China made a public commitment not to assist “in any way, any country in the development of ballistic missiles that can be used to deliver nuclear weapons.”
  • China has aided Pakistan’s nuclear and missile programs among other states. Iran, Libya, North Korea, and Saudi Arabia have also been identified as recipients of sensitive technologies and materials from China.
  • The China Nuclear Energy Industry Corporation (CNEIC)—with government authorization—has exported Miniature Neutron Source Reactors (MNSR) to Pakistan, Iran, Syria, Ghana, and Nigeria. These reactors run on highly enriched uranium fuel, albeit a fraction of what is necessary for a nuclear warhead, which has been supplied by China to recipient states.
  • There have been efforts made by China to work with those states to convert these reactors to use low enriched uranium fuel, including a 2010 agreement between the U.S. Argonne National Laboratory and the China Institute of Atomic Energy for a new facility in China to produce LEU replacement cores in MNSR's.
  • Nuclear Supplier Group (NSG) members, including the United States, saw enough improvement in China’s nuclear export behavior that they extended membership to China in 2004.
    • Nonetheless, China has sold reactors to Pakistan, as was revealed in a 2010 agreement between the two nations. This trade, however, contravenes NSG guidelines.
  • China’s bid to join the Missile Technology Control Regime failed in 2004, due to continuing concerns about Chinese missile and missile technology transactions. China, however, maintains that it voluntarily abides by the regime’s guidelines.
  • A 2017 State Department Compliance report cited that “in 2016, Chinese entities continued to supply missile programs of proliferation concern.”
  • Chinese entities have been regularly sanctioned for nonproliferation violations  by the U.S. government. For example, several Chinese entities were sanctioned under the Iran, North Korea, and Syria Nonproliferation Act (INKSNA) sanctions in 2016.
  • The United States has also, at various times, imposed sanctions on Chinese entities for missile and chemical weapons related transfers to Pakistan and Iran such as the provision of dual-use chemical weapons precursors and production equipment to Iran beginning in 1997.

Nuclear Doctrine
China was the first nuclear-weapon state to declare publicly that it will not be the first to use nuclear weapons. Beijing has emphasized that this vow stands “at any time or under any circumstances.” However, the omission of China’s “No First Use” policy from its 2013 defense white paper caused considerable concern amongst U.S. analysts. Nevertheless, in its 2015 military strategy white paper it reaffirmed its no first use policy and further pledged not to engage in a nuclear arms race. The report also states,

"China has always kept its nuclear capabilities at the minimum level required for maintaining its national security. China will optimize its nuclear force structure, improve strategic early warning, command and control, missile penetration, rapid reaction, and survivability and protection, and deter other countries from using or threatening to use nuclear weapons against China."

Regardless, some theorize that the modernization of China’s nuclear arsenal, its intent on increasing its nuclear warfare capabilities, and its posturing demonstrate a doctrine of counternuclear coercion or limited deterrence.

China has conducted 45 nuclear tests. The first test occurred Oct. 16, 1964, and the last test took place July 29, 1996.

Biological Weapons

  • China contends it is in compliance with the Biological Weapons Convention (BWC) despite U.S. allegations asserting the contrary. U.S. State Department compliance assessment reports have said that China possessed an offensive biological weapons capability prior to joining the BWC in 1984.
  • The 2015 report indicates that China "engaged during the reporting period in biological activities with potential dual-use applications. However, the information did not establish that China is engaged in activities prohibited by the BWC." The 2017 compliance report does not cite any Chinese violations.

Back to Top

Chemical Weapons

  • China has declared that it has destroyed all chemical weapon agent production facilities and solely conducts defensive chemical warfare research.
  • Beijing’s official position emphasizes the complete prohibition and destruction of chemical weapons. In the past, the U.S. government has alleged that China may be violating its Chemical Weapons Convention (CWC) commitments by secretly pursuing chemical weapons programs.
  • The State Department’s 2010 compliance report concluded that “available information does not allow the United States to confirm whether China has fully declared or explained its historical CW [chemical weapon] activities, including CW production, disposition of produced CW agents, and transfer of CW agents to another country.” The State Department's 2017 CWC report did not list any Chinese compliance issues.
  • China inherited approximately 700,000 abandoned chemical weapon (ACW) munitions from the Imperial Japanese Army at the end of World War II. Many of these ACWs are not easily located or properly stored; many of them are buried.
  • Japan, as of 2017, continues to jointly work with China to destroy these ACWs. Destruction began in March 2010. In November 2014, the Chinese Foreign Ministry urged Japan to speed up the destruction process. As of December 2014, 50,800 ACWs had been recovered in China, of which 37,373 were verifiably destroyed.

Other Arms Control and Nonproliferation Activities

Conference on Disarmament (CD)
At the 65-member CD, China expressed support for negotiation of an “effectively verifiable” fissile material cutoff treaty (FMCT) while declaring its top priority to be the prevention of an arms race in outer space (PAROS). Chinese insistence that the conference take some action on the outer space issue in parallel with any negotiations on a cutoff treaty and the U.S. opposition to that approach has, as of 2017, contributed to the stalemate of the conference over the past several years. In 2003, China said it would accept discussions on outer space rather than formal negotiations but that formulation remained unacceptable to the United States. China, however, did not agree to a 2007 compromise formula, including talks on outer space, which the United States said it would not oppose. China refused to participate in Australian and Japanese-led side meetings at the CD in 2011, insisting that the CD was the only proper conduit for FMCT negotiations. The U.S. has stated that the lack of support by China and other key countries resulted in the failure of the side meetings to make progress. China believes that a FMCT should not restrict the use of existing fissile material for weapons purposes.

Nuclear Weapons Free Zones
China has ratified additional protocols to the Latin American and Caribbean, South Pacific, African, and Central Asian nuclear weapons free zone treaties pledging not to use or threaten to use nuclear weapons against the treaty’s member states. However, China maintains a reservation to additional Protocol II of the South Pacific nuclear weapons free zone. It has not ratified the Southeast Asia nuclear weapons free zone treaty.   

Nuclear Security Summits
China participated in all four Nuclear Security Summits. China played an active role in these summits and in the 2014 NSS, President Xi Jinping put forward a Chinese approach to nuclear security for the first time.

Six-Party Talks
China played a key role in hosting and helping mediate the so-called six-party talks to achieve North Korea’s nuclear disarmament. Although those talks broke down in 2008 and have yet to resume, China maintains that they remain an effective mechanism for achieving disarmament in North Korea.  However, amidst mounting pressure and criticism from U.S. President Donald Trump’s administration for China to take charge of the North Korean threat, Chinese Foreign Ministry spokesman Geng Shuang stated, in February 2017, that “we have said many times already that the crux of the North Korean nuclear issue is the problem between the United States and North Korea,” and that “the Trump White House needs to make the first move and talk to Pyongyang.”

Joint Comprehensive Plan of Action (JCPOA)
China took part in the negotiation of the July 2015 JCPOA, which limits and rolls back Iran’s nuclear program. Despite being a “quiet negotiator” in these talks, Chinese Foreign Minister Wang Yi expressed, at the conclusion of negotiation, that “at some important points when the negotiation met with the difficulties and reached the deadlocks, China had actively explored ideas and approaches to resolve the problems and put forward its own solutions from a perspective taking into consideration of the common interests of all parties.”

The Presidential Nuclear Initiatives (PNIs) on Tactical Nuclear Weapons at a Glance

July 2017

Contacts: Daryl Kimball, Executive Director, (202) 463-8270 x107; Kingston Reif, Director for Disarmament and Threat Reduction Policy, (202) 463-8270 x104

Near the Cold War’s end, leaders in Washington and Moscow made reciprocal unilateral pledges to substantially limit and reduce their nuclear weaponry, most notably their tactical or “battlefield” nuclear weapons, such as nuclear artillery shells. President George H.W. Bush initiated these commitments, collectively known as the Presidential Nuclear Initiatives (PNIs), in September 1991 in recognition of the break up of the Eastern bloc and out of concern for the Kremlin’s ability to maintain control of its vast nuclear arsenal as political changes swept the Soviet Union. By pledging to end foreign deployments of entire categories of U.S. tactical nuclear weapons, Bush hoped that leaders in Moscow would follow suit; and they did, at least in part. All Soviet nuclear weapons were reportedly successfully consolidated on Russian soil. Still, Washington alleges Moscow has not yet fulfilled all of its PNI destruction commitments. Meanwhile, Russia opposes the continued stationing of U.S. tactical nuclear gravity bombs in Europe, which the PNIs did not cover. Despite lingering concerns about each other’s tactical nuclear weapons, the two sides have not negotiated further reductions or transparency measures for these arms since the early 1990s.

U.S. Presidential Nuclear Initiatives:

On Sept. 27, 1991, Bush announced a raft of unilateral initiatives to limit and reduce the U.S. tactical nuclear weapons arsenal. Specifically, he pledged to:

  • withdraw to the United States all ground-launched short-range weapons deployed overseas and destroy them along with existing U.S. stockpiles of the same weapons; and
  • cease deployment of tactical nuclear weapons on surface ships, attack submarines, and land-based naval aircraft during “normal circumstances.” Implicitly, the United States reserved the right to redeploy these arms in a crisis.

Soviet/Russian Presidential Nuclear Initiatives:

On Oct. 5, 1991, Soviet President Mikhail Gorbachev responded to Bush’s speech with reciprocal Soviet measures. Specifically, Gorbachev committed to:

  • eliminate all nuclear artillery munitions, nuclear warheads for tactical missiles, and nuclear mines;
  • remove all tactical nuclear weapons from surface ships and multipurpose submarines. These weapons would be stored in central storage sites along with all nuclear arms assigned to land-based naval aircraft; and
  • separate nuclear warheads from air defense missiles and put the warheads in central storage. A “portion” would be destroyed.

On Jan. 29, 1992, Russian President Boris Yeltsin reaffirmed Gorbachev’s commitments and expanded on them in response to a second round of unilateral U.S. nuclear weapons cutbacks focused on strategic forces. (Following the Soviet Union’s Dec. 25, 1991 collapse, Russia assumed responsibility for the Soviet Union’s nuclear complex and arms control commitments.) Yeltsin said Russia would:

  • eliminate a third of its sea-based tactical nuclear weapons and half of its ground-to-air nuclear missile warheads; and
  • halve its airborne tactical nuclear weapons stockpile. Pending reciprocal U.S. action, the other half of this stockpile would be taken out of service and placed in central storage depots.


A precise accounting of U.S. and Soviet/Russian fulfillment of their tactical nuclear weapons PNIs is difficult because of ambiguity, then and now, surrounding the composition, size, and location of these arms. By 1991, the United States had nearly 5,000 tactical nuclear weapons deployed overseas, most of which were assigned to NATO. Estimates on the size of the Soviet tactical nuclear arsenal at that same time ranged widely from 12,000 to nearly 21,700 weapons.

The United States completed its proposed reductions and withdrawals of deployed tactical nuclear weapons in 1992. The elimination process was finished in 2003.

As a result of the PNIs, the U.S. withdrew and destroyed around 2,000 ground-launched nuclear artillery shells and short-range ballistic missiles, all TNWs on navy surface ships and attack submarines, and on land-based naval aircraft, destroyed all nuclear depth bombs, de-alerted strategic bombers, and cancelled planned nuclear systems. By the mid-1990s, the stockpile of TNWs fell to below 1,000 warheads. Between 1990 and the end of 1994 (when the START Treaty entered into force), the U.S. nuclear stockpile of active and inactive warheads fell from 21,392 to 10,979, a 50 percent reduction.

At a Dec. 21, 1991 conference at Alma-Ata, the Soviet Republics of Belarus, Kazakhstan, and Ukraine pledged to return all Soviet tactical nuclear weapons on their territories to Russia by July 1, 1992. All three states met their commitments despite the Soviet Union’s breakup four days after these pledges were made. Otherwise, Russia has released little information substantiating its PNI activities. At the May 2005 nuclear Nonproliferation Treaty Review Conference, Moscow announced that all Russian tactical nuclear weapons “are now deployed only within the national territory and are concentrated at central storage facilities of the Ministry of Defense.” In 2007, Colonel-General Vladimir Verkhovtsev remarked, “Russia particularly committed itself to removing tactical nuclear weapons from the ground forces completely. Those weapons were also cut by 50 percent in the Air Force, by 60 percent in missile defense troops and by 30 percent on nuclear submarines of the Russian Navy,” the general said.

 Still, the Department of State has publicly questioned Russia’s PNI record. Specifically, it noted in June 2005, “Russia has failed to state publicly the status of the elimination of its nuclear artillery munitions, nuclear warheads for air defense missiles, nuclear mines, or nuclear weapons on land-based naval aviation.” These concerns were not expressed in the 2017 State Department Compliance Report, however.

Current Status:

As of 2016, the United States possesses about 500 B61 gravity bombs, 150-200 of which deployed in five European countries (Belgium, Germany, Italy, the Netherlands and Turkey). As of 2017, Russia retains approximately 1850 nonstrategic weapons, all of which are stored on Russian territory.

Since the PNIs, the United States and Russia have not agreed on additional measures to share information on or limit their tactical nuclear weapons. The two countries agreed in March 1997 to explore measures relating to tactical nuclear weapons, but nothing came of this effort. In June 2005, Russia conditioned additional talks on tactical nuclear weapons to the U.S. withdrawal of its remaining nuclear weapons in Europe. The United States has said these weapons are deployed as part of NATO policy and that a decision to withdraw them would need to be taken by all alliance members. In 2005, Congress passed legislation calling on the Bush administration to investigate measures to help Russia account for and secure its tactical arms and assess whether tactical nuclear reductions with Russia should be pursued.

In 2010, the Barack Obama administration stated that it was the goal of the United States to seek further reductions in all types of U.S. and Russian nuclear weapons—strategic and nonstrategic, deployed or nondeployed—following the conclusion of the 2010 New START talks. The 2010 NATO Strategic Concept states that the goal of the alliance is to "seek Russian agreement to increase transparency on its nuclear weapons in Europe and relocate these weapons away from the territory of NATO members." officials insist that the U.S. should first withdraw all of its tactical nuclear weapons to its national territory. In the 2010 Nuclear Posture Review, the Obama Administration announced a unilateral retirement of the Navy’s stockpile of nuclear-armed submarine launched cruise missiles (SLCMs). 

In April 2010, then-Secretary of State Hillary Clinton stated that the U.S. could remove nuclear weapons from Europe in exchange for a reduction in the size of Russia’s nonstrategic nuclear weapons arsenal. In 2013, Obama gave a speech advocating for the U.S. to work with European allies and Russia to negotiate future reductions in nonstrategic nuclear weapons.

However, to date the United States and Russia have not commenced talks regarding additional cuts on nonstrategic weapons, and a range of arms control disputes threatens to continue to obstruct progress on the matter. Russia is unlikely to discuss cuts to its nonstrategic nuclear weapons arsenal until the United States removes nonstrategic nuclear forces from Europe and agrees to limitations of its ballistic missile defense program.

Proposed Major U.S. Arms Export Agreements, January 2016—December 2016

Countries which sought the highest values in U.S. arms exports in 2016 and their specific requests

The value of proposed U.S. major conventional arms sales agreements totaled nearly $63 billion in 2016—the second highest amount during Barack Obama’s 8-year presidency. More than two-thirds (nearly $44 billion) involved just four Gulf Cooperation Council (GCC) countries—Qatar, Kuwait, the United Arab Emirates (UAE), and Saudi Arabia—that each requested greater than $5 billion in sales. Other state requests amounting to at least $1 billion came from Australia, Iraq, Japan, Norway and the United Kingdom. In total, notifications were made involving 26 different countries plus NATO in 2016.

In 2016, the U.S. Congress approved the sale to Qatar of the new F-15QA fighter aircraft to Qatar, which is likely to be a variant of the F-15 Strike Eagle shown here. (Photo: U.S. Air Force/Staff Sgt. Aaron Allmon II)The United States conducts government-to-government arms transfers through the Defense Department’s Foreign Military Sales (FMS) program. Not all notified sales result in final transactions. Under the 1976 Arms Export Control Act, Congress must be notified of proposed sales of “major defense equipment”—as defined on the U.S. Munitions List—that equals or exceeds $14 million; defense articles and services that are not defined as “major defense equipment” that total $50 million or more; and construction or design services amounting to or surpassing $200 million.[1] However, if the proposed sale involves NATO members, Australia, Israel, Japan, South Korea, or New Zealand, the notification thresholds are $25 million for major defense equipment, $100 million for other defense articles and services, and $300 million for construction or design services.[2] Once notified, Congress has 30 calendar days (15 in the case of NATO members, Australia, Israel, Japan, South Korea, and New Zealand) to block a sale by passing a joint resolution of disapproval, although it has never stopped a sale once formally notified.

Arms sales notified in 2016 appeared consistent with efforts made by President Obama to gain regional support from GCC members during the negotiation of the Joint Comprehensive Plan of Action addressing Iran’s nuclear program. In May 2015, Obama pledged to “help our Gulf partners improve their own capacity to defend themselves” and to “streamline and expedite the transfer of critical defense capabilities.” 

In 2016, Qatar requested the most expensive package of arms sales agreements – more than $22 billion – with weapons, training, and support for 72 F-15QA fighter aircraft comprising the lion’s share ($21.5 billion). Other requests included support and engines for 8 C-17 heavy lift aircraft, 50 Javelin guided missiles, as well as fast patrol boats. 

Kuwait followed Qatar as the only country requesting more than $10 billion in arms sales in 2016 (approximately $12.45 billion). Most of the proposed sales to Kuwait consisted of 40 F/A 18E/F Super Hornets and related equipment, training and support ($10.1 billion). Kuwait also requested equipment to recapitalize 218 M1A2 tanks, support for its F-18 C/D fighter aircraft, radar systems, and 750 Joint Direct Attack Munition (JDAM) tail kits designed to make gravity bombs into precision-guided weapons.

Both the UAE and Saudi Arabia requested sales valued at approximately $5 billion each. Of all proposed sales in 2016, those to Riyadh proved most controversial. In September, 27 senators voted unsuccessfully to block a proposed $1.15 billion sale to provide or repair 153 tanks. In December, the administration notified Congress of a larger $3.5 billion potential sale comprised of 48 CH-47F Chinook cargo helicopters and related equipment, training and support. In 2015 and 2016, Saudi Arabia faced national and international condemnation for its conduct leading a coalition fighting in Yemen, during which hospitals and other civilian areas were attacked by Saudi forces. 

The UAE’s 2016 request included 37 Apache helicopters, 400 Hellfire missiles, and more than 14,000 bombs among its primarily airpower-focused potential purchases.

Below is a chart of the top five countries that sought the highest values in U.S. arms exports in 2016, along with some of their specific requests.

1. The Department of State is also required to report to Congress any commercial sales it approves of “major defense equipment” that amount to $14 million or more, defense articles and services that equal or exceed $50 million, and any items defined as “significant military equipment.” As in the case of FMS sales, Congress can block the sale with a joint resolution of disapproval within 30 calendar days of notification (15 in the case of NATO members, Australia, Israel, Japan, New Zealand, and South Korea). Commercially licensed sales of firearms controlled under category I of the U.S. Munitions List valued at $1 million or more must also be notified to Congress but are not considered here. There are no official compilations of commercial agreement data comparable to the FMS notifications and what exists is often incomplete and less precise than data on government-to-government transactions (Theohary, Catherine A., Conventional Arms Transfers to Developing Nations, 2008-2015, Washington, D.C., Congressional Research Service, December 19, 2016, p. 16). The annual Section 655 report, prepared by the State and Defense Departments for Congress, details commercial licenses approved, but states have four years to act under the licenses. The State Department’s Directorate of Defense Trade Controls has final responsibility for license applications for commercial defense trade exports and all issues related to defense trade compliance, enforcement, and reporting.

2. Congress approved the higher notification thresholds for NATO members, Australia, Japan, and New Zealand in legislation passed in September 2002. South Korea was added to this list in 2008, and Israel was added in 2010. Congress, however, is free to pass legislation to block or modify an arms sale at any time up to the point of delivery of the items involved.

UN Security Council Resolutions on North Korea

April 2018

Contact: Kelsey Davenport, Director for Nonproliferation Policy, (202) 463-8270 x102

The United Nations Security Council has adopted nine major sanctions resolutions on North Korea in response to the country’s nuclear and missile activities since 2006.

Each resolution condemns North Korea’s latest nuclear and ballistic missile activity and calls on North Korea to cease its illicit activity, which violates previous UN Security Council resolutions. All nine resolutions were unanimously adopted by the Security Council and all but Resolution 2087 (January 2013) contain references to acting under Chapter VII, Article 41 of the United Nations Charter.

In addition to imposing sanctions, the resolutions give UN member states the authority to interdict and inspect North Korean cargo within their territory, and subsequently seize and dispose of illicit shipments.

The resolutions also call upon North Korea to rejoin the nuclear Non-Proliferation Treaty (NPT), which it acceded to in 1985 but withdrew from in 2003 after U.S. allegations that the country was pursuing an illegal uranium enrichment program. The Security Council also has called for North Korea to return to negotiations in the Six-Party Talks, which include South Korea, North Korea, China, Japan, Russia and the United States. The Six-Party talks, which took place from 2003-2009, resulted in a joint statement on denuclearization. North Korea also dismantled its plutonium-producing reactor as part of the process, although it has subsequently restarted the reactor. For more on the Six-Party talks, click here.

The United Nations monitors implementation of North Korea sanctions through the 1718 Committee, established by Security Council Resolution 1718 in 2006 and a Panel of Experts, established by Security Council Resolution 1874 in 2009. The panel produces regular reports to the Security Council on the status of the sanctions and enforcement.

Prior to passing the first sanctions resolution in 2006, the Security Council passed several resolutions condemning North Korea’s nuclear and missile activities. In response to North Korea’s announcement of intent to withdraw from the NPT in 1993, the Security Council passed Resolution 825, urging North Korea to remain party to the NPT and to honor its nonproliferation obligations under the treaty. Resolution 1695 was passed in 2006 in response to ballistic missile launches in July, and calls on North Korea to suspend activities related to its ballistic missile program. Additional Security Council resolutions on North Korea serve to extend the 1718 Committee mandate. They are not included in this list, but can be found here.

Resolution 1874’s Principal Sanctions

Sanctions in Resolution 1874 built off several measures first laid out in Resolution 1718. The resolution expanded the arms embargo by banning all imports and exports of weapons, excluding small arms (which required Security Council notification).

Member states were also authorized to:

  • Inspect North Korea cargo on land, air, and sea, if the state has reason to believe that it contains prohibited items and seize any prohibited materials or technologies

Known as the ‘Panel of Experts,’ the group was initially given a mandate for one year and was required to report regularly to the Sanctions Committee on possible violations and recommendations for improving implementation. Later resolutions extended the mandate of the Panel of Experts.

Back to the top. 

Security Council Resolution 2087

The Security Council unanimously adopted Resolution 2087 on January 22, 2013 after a successful North Korean satellite launch on December 12, 2012. The launch was a violation of Resolutions 1718 (2006) and 1874 (2009), which prohibited any further development of technology applicable to North Korea’s ballistic missile programs. The full text of Resolution 2087 is available here.

Resolution 2087’s Principal Provisions

Resolution 2087 called for other states to “remain vigilant” in monitoring individuals and entities associated with the North Korean regime. It also directed the sanctions committee to issue an Implementation Assistance Notice if a vessel refused to allow an inspection authorized by its flag state.

Resolution 2087’s Principal Sanctions

Resolution 2087 built on sanctions included in Resolutions 1718 and 1874 including:

  • Clarifying the catch-all provision

Additionally, this resolution

  • Expressed concern that North Korea was abusing immunities granted to its diplomats by the Vienna Convention on Diplomatic and Consular Relations
  • Welcomed the Financial Action Task Force’s new recommendation on targeted financial sanctions related to proliferation and urged member states to apply the recommendations

Resolution 2094’s Principal Sanctions

Resolution 2094 expands a number of sanctions measures from earlier resolutions, such as adding nuclear and missile dual-use technologies and luxury goods to the list of banned imports.

Resolution 2094 also designated additional individuals and entities for asset freezes and the travel ban and expanded the designation criteria to include persons or entities suspected of acting on the behalf or controlled by any persons or entities already sanctioned.

The resolution aims to make it more difficult for North Korea to make further progress in its nuclear and ballistic missile programs by hindering its access to hard cash and technological equipment needed to build weapons and pursue uranium enrichment.

The resolution also strengthened the interdiction and oversight authorities for member states by:

  • calling for states to inspect and detain any suspected cargo or shipments to or from North Korea that transit through their territory, if the cargo is suspected to contain bulk cash or material that could be used in a nuclear program.
  • Directing states to enhance vigilance over North Korea’s diplomatic personnel

New financial sanctions included in the resolution:
