For years, the United States and the international community have tried to negotiate an end to North Korea’s nuclear and missile development and its export of ballistic missile technology. Those efforts have been replete with periods of crisis, stalemate, and tentative progress towards denuclearization, and North Korea has long been a key challenge for the global nuclear nonproliferation regime.
The United States has pursued a variety of policy responses to the proliferation challenges posed by North Korea, including military cooperation with U.S. allies in the region, wide-ranging sanctions, and non-proliferation mechanisms such as export controls. The United States also engaged in two major diplomatic initiatives to have North Korea abandon its nuclear weapons efforts in return for aid.
In 1994, faced with North Korea’s announced intent to withdraw from the nuclear Nonproliferation Treaty (NPT), which requires non-nuclear weapon states to forswear the development and acquisition of nuclear weapons, the United States and North Korea signed the Agreed Framework. Under this agreement, Pyongyang committed to freezing its illicit plutonium weapons program in exchange for aid.
Following the collapse of this agreement in 2002, North Korea claimed that it had withdrawn from the NPT in January 2003 and once again began operating its nuclear facilities.
The second major diplomatic effort were the Six-Party Talks initiated in August of 2003 which involved China, Japan, North Korea, Russia, South Korea, and the United States. In between periods of stalemate and crisis, those talks arrived at critical breakthroughs in 2005, when North Korea pledged to abandon “all nuclear weapons and existing nuclear programs” and return to the NPT, and in 2007, when the parties agreed on a series of steps to implement that 2005 agreement.
Those talks, however, broke down in 2009 following disagreements over verification and an internationally condemned North Korea rocket launch. Pyongyang has since stated that it would never return to the talks and is no longer bound by their agreements. The other five parties state that they remain committed to the talks, and have called for Pyongyang to recommit to its 2005 denuclearization pledge.
In January 2018, another diplomatic effort began when North Korean leader Kim Jong Un declared the country's nuclear arsenal "complete" and offered to discuss with Seoul North Korea's participation in the South Korean Olympics. North Korea's delegation to the Olympics included Kim Jong Un's sister, who met with South Korean President Moon Jae-in. That meeting led to a sustained inter-Korean dialouge, including a meeting between Kim Jong Un and Moon Jae-in April 27 that produced a declaration referencing the shared goal of denuclearization of the Korean peninsula.
During a high-level meeting with South Korean officials in Pyongyang in March, Kim Jong Un conveyed his interest in meeting with U.S. President Donald Trump. Trump accepted the offer and the two leaders will meet June 12 in Singapore.
The following chronology summarizes in greater detail developments in North Korea’s nuclear and missile programs, and the efforts to end them, since 1985.
December 12, 1985: North Korea accedes to the nuclear Nonproliferation Treaty (NPT) but does not complete a safeguards agreement with the International Atomic Energy Agency (IAEA). Under Article III of the NPT, North Korea has 18 months to conclude such an arrangement. In coming years, North Korea links adherence to this provision of the treaty to the withdrawal of U.S. nuclear weapons from South Korea.
September 27, 1991: President George Bush announces the unilateral withdrawal of all naval and land-based tactical nuclear weapons deployed abroad. Approximately 100 U.S. nuclear weapons had been based in South Korea. Eight days later, Soviet President Mikhail Gorbachev reciprocates.
November 8, 1991: In response to President Bush’s unilateral move, President Roh Tae Woo of South Korea announces the Declaration on the Denuclearization of the Korean Peninsula, under which South Korea promises not to produce, possess, store, deploy, or use nuclear weapons. In addition, the declaration unilaterally prohibits South Korea from possessing nuclear reprocessing or uranium enrichment facilities. These promises, if enacted, would satisfy all of North Korea’s conditions for allowing IAEA inspections of its nuclear facilities.
January 20, 1992: The two Koreas sign the South-North Joint Declaration on the Denuclearization of the Korean Peninsula. Under the declaration, both countries agree not to “test, manufacture, produce, receive, possess, store, deploy or use nuclear weapons” or to “possess nuclear reprocessing and uranium enrichment facilities.” They also agree to mutual inspections for verification.
January 30, 1992: More than six years after signing the NPT, North Korea concludes a comprehensive safeguards agreement with the IAEA.
March 6, 1992: The United States imposes sanctions on North Korea’s Lyongaksan Machineries and Equipment Export Corporation and Changgwang Sinyong Corporation for missile proliferation activities.*
April 9, 1992: North Korea ratifies the safeguards agreement with the IAEA.
May 4, 1992: North Korea submits its nuclear material declarations to the IAEA, declaring seven sites and some 90 grams of plutonium that could be subject to IAEA inspection. Pyongyang claims that the nuclear material was the result of reprocessing 89 defective fuel rods in 1989. The IAEA conducted inspections to verify the completeness of this declaration from mid-1992 to early 1993.
June 23, 1992: The United States imposes “missile sanctions” on the North Korean entities sanctioned in March.*
September 1992: IAEA inspectors discover discrepancies in North Korea’s “initial report” on its nuclear program and ask for clarification on several issues, including the amount of reprocessed plutonium in North Korea.
February 9, 1993: The IAEA demands special inspections of two sites that are believed to store nuclear waste. The request is based on strong evidence that North Korea has been cheating on its commitments under the NPT. North Korea refuses the IAEA’s request.
March 12, 1993: Amid demands for special inspections, North Korea announces its intention to withdraw from the NPT in three months, citing Article X provisions that allow withdrawal for supreme national security considerations.
April 1, 1993: The IAEA declares that North Korea is not adhering to its safeguards agreement and that it cannot guarantee that North Korean nuclear material is not being diverted for nonpeaceful uses.
June 11, 1993: Following talks with the United States in New York, North Korea suspends its decision to pull out of the NPT just before the withdrawal would have become legally effective. North Korea also agrees to the full and impartial application of IAEA safeguards.
For its part, the United States grants assurances against the threat and use of force, including nuclear weapons. Washington also promises not to interfere with North Korea’s internal affairs.
July 19, 1993: After a second round of talks with the United States, North Korea announces in a joint statement that it is “prepared to begin consultations with the IAEA on outstanding safeguards and other issues” and that it is ready to negotiate IAEA inspections of its nuclear facilities. The joint statement also indicates that Pyongyang might consider a deal with the United States to replace its graphite nuclear reactors with light-water reactors (LWRs), which are proliferation resistant.
Late 1993: The Central Intelligence Agency (CIA) and the Defense Intelligence Agency estimate that North Korea had separated about 12 kilograms of plutonium. This amount is enough for at least one or two nuclear weapons.
January 1994: The director of the CIA estimates that North Korea may have produced one or two nuclear weapons.
February 15, 1994: North Korea finalizes an agreement with the IAEA to allow inspections of all seven of its declared nuclear facilities, averting sanctions by the United Nations Security Council.
March 1, 1994: IAEA inspectors arrive in North Korea for the first inspections since 1993.
March 21, 1994: Responding to North Korea’s refusal to allow the inspection team to inspect a plutonium reprocessing plant at Yongbyon, the IAEA Board of Governors approves a resolution calling on North Korea to “immediately allow the IAEA to complete all requested inspection activities and to comply fully with its safeguards agreements.”
May 19, 1994: The IAEA confirms that North Korea has begun removing spent fuel from its 5-megawatt nuclear research reactor even though international monitors were not present. The United States and the IAEA had insisted that inspectors be present for any such action because spent fuel can potentially be reprocessed for use in nuclear weapons.
June 13, 1994: North Korea announces its withdrawal from the IAEA. This is distinct from pulling out of the NPT—North Korea is still required to undergo IAEA inspections as part of its NPT obligations. The IAEA contends that North Korea’s safeguards agreement remains in force. However, North Korea no longer participates in IAEA functions as a member state.
June 15, 1994: Former U.S. President Jimmy Carter negotiates a deal with North Korea in which Pyongyang confirms its willingness to “freeze” its nuclear weapons program and resume high-level talks with the United States. Bilateral talks are expected to begin, provided that North Korea allows the IAEA safeguards to remain in place, does not refuel its 5-megawatt nuclear reactor, and does not reprocess any spent nuclear fuel.
July 9, 1994: North Korean President Kim Il Sung dies and is succeeded by his son, Kim Jong Il.
August 12, 1994: An “agreed statement” is signed that establishes a three-stage process for the elimination of North Korea’s nuclear weapons program. In return, the United States promises to move toward normalized economic and diplomatic relations and assures North Korea that it will provide assistance with the construction of proliferation-resistant LWRs to replace North Korea’s graphite-moderated reactors.
October 21, 1994: The United States and North Korea conclude four months of negotiations by adopting the “Agreed Framework” in Geneva. To resolve U.S. concerns about Pyongyang’s plutonium-producing reactors and the Yongbyon reprocessing facility, the agreement calls for North Korea to freeze and eventually eliminate its nuclear facilities, a process that will require dismantling three nuclear reactors, two of which are still under construction. North Korea also allows the IAEA to verify compliance through “special inspections,” and it agrees to allow 8,000 spent nuclear reactor fuel elements to be removed to a third country.
In exchange, Pyongyang will receive two LWRs and annual shipments of heavy fuel oil during construction of the reactors. The LWRs will be financed and constructed through the Korean Peninsula Energy Development Organization (KEDO), a multinational consortium.
Calling for movement toward full normalization of political and economic relations, the accord also serves as a jumping-off point for U.S.-North Korean dialogue on Pyongyang’s development and export of ballistic missiles, as well as other issues of bilateral concern.
November 28, 1994: The IAEA announces that it had confirmed that construction has been halted at North Korea’s Nyongbyon and Taochon nuclear facilities and that these facilities are not operational.
March 9, 1995:KEDO is formed in New York with the United States, South Korea, and Japan as the organization’s original members.
January 1996: North Korea agrees in principle to a meeting on missile proliferation issues, which had been requested in a letter by Deputy Assistant Secretary of State for East Asian and Pacific Affairs Thomas Hubbard. However, Pyongyang contends that the United States would have to ease economic sanctions before it could agree on a date and venue for the talks.
In testimony before a House International Relations subcommittee on March 19, Assistant Secretary of State for East Asian and Pacific Affairs Winston Lord says that Washington is willing to ease economic sanctions if progress is made on the missile export issue.
April 21-22, 1996: The United States and North Korea meet in Berlin for their first round of bilateral missile talks. The United States reportedly suggests that North Korea should adhere to the Missile Technology Control Regime (MTCR), a voluntary international agreement aimed at controlling sales of ballistic missile systems, components, and technology. North Korea allegedly demands that the United States provide compensation for lost missile-related revenue.
May 24, 1996: The United States imposes sanctions on North Korea and Iran for missile technology-related transfers. The sanctions prohibit any imports or exports to sanctioned firms and to those sectors of the North Korean economy that are considered missile-related. The pre-existing general ban on trade with both countries makes the sanctions largely symbolic.*
October 16, 1996: After detecting North Korean preparations for a test of its medium-range Nodong missile, the United States deploys a reconnaissance ship and aircraft to Japan. Following several meetings in New York between U.S. and North Korean diplomats, the State Department confirms on November 8 that the missile test has been canceled.
June 11-13, 1997: The second round of U.S.-North Korean missile talks takes place in New York, with U.S. negotiators pressing North Korea not to deploy the Nodong missile and to end sales of Scud missiles and their components. The parties reach no agreement but reportedly lay the foundation for future talks.
August 6, 1997: The United States imposes new sanctions on two additional North Korean entities for unspecified missile-proliferation activities.*
February 25, 1998: At his inaugural speech, South Korean President Kim Dae-jung announces his “sunshine policy,” which strives to improve inter-Korean relations through peace, reconciliation, and cooperation.
April 17, 1998: The United States imposes sanctions on North Korea and Pakistan in response to Pyongyang’s transfer of missile technology and components to Pakistan’s Khan Research Laboratory.*
June 16, 1998: The official Korean Central News Agency reports that Pyongyang will only end its missile technology exports if it is suitably compensated for financial losses.
July 15, 1998: The bipartisan Rumsfeld Commission concludes that the United States may have “little or no warning” before facing a long-range ballistic missile threat from “rogue states,” such as North Korea and Iran.
August 31, 1998: North Korea launches a three-stage Taepo Dong-1 rocket with a range of 1,500-2,000 kilometers that flies over Japan. Pyongyang announces that the rocket successfully placed a small satellite into orbit, a claim contested by U.S. Space Command. Japan suspends signature of a cost-sharing agreement for the Agreed Framework’s LWR project until November 1998. The U.S. intelligence community admits to being surprised by North Korea’s advances in missile-staging technology and its use of a solid-rocket motor for the missile’s third stage.
October 1, 1998: The third round of U.S.-North Korean missile talks begins in New York but makes little progress. The United States repeats its request for Pyongyang to terminate its missile programs in exchange for relief from economic sanctions. North Korea rejects the U.S. proposal on the grounds that the lifting of sanctions is implicit in the 1994 Agreed Framework.
November 12, 1998: President Bill Clinton appoints former Secretary of Defense William Perry to serve as North Korea policy coordinator—a post established by the 1999 Defense Authorization Act. Perry immediately undertakes an interagency review of U.S. policy toward North Korea and begins consultations with South Korea and Japan aimed at forming a unified approach to dealing with Pyongyang.
December 4-11, 1998: The United States and North Korea hold talks to address U.S. concerns about a suspected underground nuclear facility at Kumchang-ni. Pyongyang reportedly accepts in principle the idea of a U.S. inspection of the site but is unable to agree with U.S. proposals for “appropriate compensation.”
February 2, 1999: CIA Director George Tenet testifies before the Senate Armed Services Committee that, with some technical improvements, North Korea would be able to use the Taepo Dong-1 to deliver small payloads to parts of Alaska and Hawaii. Tenet also says that Pyongyang’s Taepo Dong-2, if it had a third stage like the Taepo Dong-1, would be able to deliver large payloads to the continental United States, albeit with poor accuracy.
March 29-31, 1999: U.S. and North Korean officials hold a fourth round of missile talks in Pyongyang. The United States again expresses concern over North Korea’s missile development and proliferation activities and proposes a deal exchanging North Korean restraint for U.S. sanctions relief. U.S. officials describe the talks as “serious and intensive” but succeed only in reaching agreement to meet again at an unspecified date.
April 25, 1999: The United States, South Korea, and Japan establish the Trilateral Coordination and Oversight Group to institutionalize close consultation and policy coordination in dealing with North Korea.
May 20-24, 1999: A U.S. inspection team visits the North Korean suspected nuclear site in Kumchang-ni. According to the State Department, the team finds no evidence of nuclear activity or violation of the Agreed Framework.
May 25-28, 1999: Traveling to Pyongyang as a presidential envoy, Perry meets with senior North Korean political, diplomatic, and military officials to discuss a major expansion in bilateral relations if Pyongyang is willing to address U.S. security concerns. Perry delivers a letter from President Clinton to North Korean leader Kim Jong Il, but the two do not meet. Perry reportedly calls on North Korea to satisfy U.S. concerns about ongoing nuclear weapons-related activities that are beyond the scope of the Agreed Framework and about ballistic missile development and proliferation in exchange for the lifting of U.S. sanctions, normalization of diplomatic relations, and potentially some form of security guarantee.
September 7-12, 1999: During talks in Berlin, North Korea agrees to a moratorium on testing any long-range missiles for the duration of talks with the United States. The United States agrees to a partial lifting of economic sanctions on North Korea. The two parties agree to continue high-level discussions. (Sanctions are not actually lifted until June 2000.)
September 9, 1999: A U.S. National Intelligence Estimate reports that North Korea will “most likely” develop an ICBM capable of delivering a 200-kilogram warhead to the U.S. mainland by 2015.
September 15, 1999: North Korean policy coordinator Perry submits his review of U.S. policy toward North Korea to Congress and releases an unclassified version of the report on October 12. The report recommends “a new, comprehensive and integrated approach to…negotiations with the [Democratic People’s Republic of Korea] DPRK,” which would involve a coordinated reduction in isolation by the United States and its allies in a “step-by-step and reciprocal fashion.” Potential engagement mechanisms could include the normalization of diplomatic relations and the relaxation of trade sanctions.
November 19, 1999: The United States and North Korea meet in Berlin for talks on bilateral relations and preparations for a North Korean high-level visit to the United States.
December 15, 1999: Five years after the Agreed Framework was signed, KEDO officials sign a turn-key contract with the Korea Electric Power Corporation to begin construction on the two LWRs in Kumho, North Korea. KEDO officials attribute the delay in signing the contract to complex legal and financial challenges and the tense political climate generated by the North Korean Taepo Dong-1 test in August 1998.
April 6, 2000: The United States imposes sanctions on a North Korean firm, Changgwang Sinyong Corporation, for proliferating MTCR Category I items, possibly to Iran. Category I items include complete missile systems with ranges exceeding 300 kilometers and payloads over 500 kilograms, major subsystems, rocket stages or guidance systems, production facilities for MTCR-class missiles, or technology associated with such missiles.*
May 25-27, 2000: The United States conducts its second inspection of the Kumchang-ni site. The inspection team found that conditions had not changed since the first inspection in May 1999.
June 15, 2000: Following a historic summit, North and South Korea sign a joint declaration stating they have “agreed to resolve” the question of reunification of the Korean Peninsula. The agreement includes promises to reunite families divided by the Korean War and to pursue other economic and cultural exchanges. No commitments are made regarding nuclear weapons or missile programs or military deployments in the Demilitarized Zone.
June 19, 2000: Apparently encouraged by the North-South summit, the United States relaxes sanctions on North Korea, allowing a “wide range” of trade in commercial and consumer goods, easing restrictions on investment, and eliminating prohibitions on direct personal and commercial financial transactions. Sanctions related to terrorism and missile proliferation remain in place. The next day, North Korea reaffirms its moratorium on missile tests.
July 12, 2000: The fifth round of U.S.-North Korean missile talks in Kuala Lumpur end without resolution. During the meeting, North Korea repeats its demand for compensation, stated as $1 billion per year, in return for halting missile exports. The United States rejects this proposal but says that it is willing to move toward “economic normalization” in return for addressing U.S. concerns.
July 19, 2000: During a meeting with Russian President Vladimir Putin, Kim Jong Il reportedly promises to end his country’s missile program in exchange for assistance with satellite launches from countries that have expressed concern about North Korea’s missile program.
July 28, 2000: At the Association of Southeast Asian Nations Regional Forum in Bangkok, Thailand, Secretary of State Madeleine Albright engages in a “substantively modest” meeting with North Korean Foreign Minister Paek Nam Sun, the highest level of exchange to date. Paek gives no additional details about North Korea’s purported offer to end its missile program in return for space-launch assistance.
August 13, 2000: Kim Jong Il tells a meeting of 46 South Korean media executives in Pyongyang that his missile proposal was meant “in humor, while talking about science and state-of-the-art technologies,” according to the Korea Times. The report of the event is widely interpreted as undercutting the seriousness of Kim’s offer; however, English-language excerpts of Kim’s speech seem to confirm the offer: “I told…Putin that we would stop developing rockets when the United States comes forward and launches our satellites.”
August 28, 2000: U.S. Ambassador Wendy Sherman travels to Moscow to confirm the details of Kim Jong Il’s apparent missile proposal with her Russian counterparts. At a September 8 briefing, a senior State Department official says the United States is taking the North Korean offer “very seriously.”
September 27, 2000: U.S.-North Korean talks resume in New York on nuclear issues, missiles, and terrorism. The two countries issue a joint statement on terrorism, a move that indicates progress toward removing North Korea from the State Department’s terrorism list.
October 9-12, 2000: Kim Jong Il’s second-in-command, Vice Marshal Jo Myong Rok, visits Washington as a special envoy. He delivers a letter to President Clinton and meets with the secretaries of state and defense. The move is seen as an affirmation of Kim’s commitment to improving U.S.-North Korean ties.
October 12, 2000: The United States and North Korea issue a joint statement noting that resolution of the missile issue would “make an essential contribution to fundamentally improved relations” and reiterating the two countries’ commitment to implementation of the Agreed Framework. The statement also says that Albright will visit North Korea in the near future to prepare for a possible visit by President Clinton.
October 24, 2000: Secretary Albright concludes a two-day visit to Pyongyang to meet with Kim Jong Il. During the visit, Kim says that North Korea would not further test the Taepo Dong-1 missile. In addition to discussing Pyongyang’s indigenous missile program, the talks cover North Korean missile technology exports, nuclear transparency, the normalization of relations, and a possible trip by President Clinton to Pyongyang.
November 1-3, 2000: A seventh round of missile talks between Pyongyang and Washington ends without an agreement in Kuala Lumpur, Malaysia. The failure to build upon the momentum derived from Secretary Albright's recent meeting with Kim Jong-Il diminished hopes of a presidential trip to North Korea before the end of President Clinton's term.
December 28, 2000: President Clinton announces that he will not travel to North Korea before the end of his term, citing "insufficient time to complete the work at hand." According to a March 6 New York Times article, Clinton's national security adviser Sandy Berger was hesitant to have the president leave the country during the presidential election dispute, which he deemed "a potential 'constitutional crisis.'"
January 2, 2001: The United States imposes sanctions on North Korea’s Changgwang Sinyong Corporation for violation of the Iran Nonproliferation Act of 2000.*
March 6, 2001: At a joint press briefing with the Swedish foreign minister, Secretary of State Colin Powell says that the administration “plan[s] to engage with North Korea to pick up where President Clinton left off. Some promising elements were left on the table and we will be examining those elements.”
March 7, 2001: In a New York Times op-ed, Wendy Sherman, former special adviser to the president and secretary of state for North Korea policy, writes that a deal with North Korea to eliminate its medium- and long-range missiles and end its missile exports had been “tantalizingly close” at the end of the Clinton administration.
After a working meeting with South Korean President Kim Dae-jung at the White House, President George W. Bush tells reporters that he “look[s] forward to, at some point in the future, having a dialogue with the North Koreans, but that any negotiation would require complete verification of the terms of a potential agreement.” According to Clinton administration officials, the issue of how to verify a missile deal remained one of the final stumbling blocks to a successful arrangement. Bush also questions whether Pyongyang is “keeping all terms of all agreements.”
Just prior to Bush’s comments, Powell amended his remarks from the previous day, noting that if “there was some suggestion that imminent negotiations are about to begin—that is not the case.”
March 13, 2001: North Korea, apparently reacting to Washington’s new tone, cancels ministerial-level talks with Seoul. The talks were intended to promote further political reconciliation.
March 15, 2001: Pyongyang threatens to “take thousand-fold revenge” on the United States “and its black-hearted intention to torpedo the dialogue between north and south [Korea].” The statement, issued by the Korean Central News Agency, called Washington’s new policies “hostile” and noted that Pyongyang remains “fully prepared for both dialogue and war.”
May 3, 2001: At a press conference in Pyongyang, a European Union delegation headed by Swedish Prime Minister Göran Persson reports that Kim Jong Il pledged that he will extend Pyongyang’s moratorium on missile testing until 2003 and that Kim was “committed” to a second inter-Korean summit.
June 6, 2001: In a press release, President Bush announces the completion of his administration’s North Korea policy review and its determination that “serious discussions” on a “broad agenda” should be resumed with Pyongyang. Bush states his desire to conduct “comprehensive” negotiations, including “improved implementation of the Agreed Framework,” “verifiable constraints” on North Korea’s missile programs, a ban on North Korea’s missile exports, and “a less threatening conventional military posture.”
June 13, 2001: U.S. Special Envoy Jack Pritchard meets in New York with the North Korean representative to the UN, Hyong-ch’ol Yi, to make arrangements for bilateral talks.
June 26, 2001: The State Department announces sanctions under the Iran Nonproliferation Act of 2000 on North Korea’s Changgwang Sinyong Corporation, for unspecified missile-related transfers to Iran. The announcement represents the second time that sanctions had been imposed under the act, the first also being on Changgwang Sinyong on January 2.
The sanctions prohibit any U.S. entity from doing business with the North Korean firm, which has been punished several times previously under more general missile transfer sanctions. However, the sanctions are largely symbolic, as Changgwang Sinyong is still subject to the active sanctions imposed on January 2, 2001, and missile sanctions that were imposed on April 6, 2000.*
July 6, 2001: Deputy Secretary of State Richard Armitage confirms that North Korea tested a rocket “motor engine” in late June, but that there was “nothing in itself wrong with that,” nor did the administration consider the test to have violated Pyongyang’s testing moratorium.
August 4, 2001: During a meeting in Moscow with President Putin, Kim Jong Il reaffirms his pledge to maintain a moratorium on ballistic missile flight-tests until 2003.
January 29, 2002: In his State of the Union address, President Bush criticized North Korea for “arming with missiles and weapons of mass destruction, while starving its citizens.” Bush characterized North Korea, along with Iraq and Iran, as constituting an “axis of evil, arming to threaten the peace of the world.”
February 5, 2002: At a Senate Foreign Relations Committee hearing, Powell reiterates the administration's policy that it is willing to resume a dialogue with North Korea at "any time, any place, or anywhere without any preconditions." Powell also confirms that the administration believes that Pyongyang continues to "comply with the [missile flight-test] moratorium they placed upon themselves and stay within the KEDO agreement," which is also known as the Agreed Framework.
March 15, 2002: Following reports that the U.S. nuclear posture review discusses the use of nuclear weapons against North Korea, Pyongyang's state-run press organ announces that, if the United States "tries to use nuclear weapons" against North Korea, it will be compelled to "examine all the agreements" reached with the United States. The report says that, "if the U.S. inflicts nuclear holocaust upon [North Korea], the former's mainland will not be safe either."
April 1, 2002: President Bush issues a memorandum stating that he will not certify North Korea's compliance with the Agreed Framework. However, for national security considerations, Bush waives applicable U.S. law prohibiting Washington from funding KEDO, allowing the United States to continue financially supporting the Agreed Framework.
July 2, 2002: The United States cancels a planned delegation visit to North Korea, citing Pyongyang’s failure to respond to a proposed July 10 meeting date, as well as a June 29 naval skirmish between North and South Korea.
July 31, 2002: Powell meets briefly with Foreign Minister Paek Nam Sun during the Association of Southeast Asian Nations Regional Forum meeting in Brunei, generating speculation that a U.S. envoy will visit North Korea. It is the highest-level exchange between the two countries since the Bush administration took office.
August 7, 2002: KEDO holds a ceremony to mark the pouring of the concrete foundation for the first LWR that the United States agreed to provide North Korea under the Agreed Framework. Jack Pritchard, the U.S. representative to KEDO and State Department special envoy for negotiations with North Korea, attends the ceremony. Pritchard is the most senior U.S. official to visit North Korea since former Secretary of State Albright in October 2000.
The United States urges North Korea to comply with IAEA safeguarding procedures for all its nuclear facilities as soon as possible, but Pyongyang states that it will not do so for at least three years, the Japanese newspaper Nihon Keizai Shimbun reports August 8. A North Korean Foreign Ministry spokesman also states that delays in completing the reactor project might motivate Pyongyang to pull out of the agreement.
August 16, 2002: The United States imposes sanctions on Changgwang Sinyong Corporation of North Korea and on the North Korean government itself for transferring missile technology to Yemen. White House Press Secretary Ari Fleischer states August 23 that the sanctions were a “pro forma requirement under the law for the State Department” and that Washington remains willing to “talk with North Korea any time, any place.”
August 31, 2002: Responding to an August 29 speech by Undersecretary of State for Arms Control and International Security John Bolton, North Korea says that “if the U.S. has a will to drop its hostile policy toward the DPRK it will have dialogue…the ball is in the court of the U.S. side.” Bolton had criticized Pyongyang’s missile, nuclear, and biological weapons programs.
September 17, 2002: North Korea announces that it will indefinitely extend its moratorium on missile testing as part of the North Korea-Japan Pyongyang Declaration signed during a meeting between Japanese Prime Minister Junichiro Koizumi and North Korean leader Kim Jong Il.
A portion of the North Korea-Japan declaration references nuclear weapons, saying that the two countries “affirmed the pledge to observe all the international agreements for a comprehensive solution to the nuclear issue on the Korean Peninsula.” It is unclear whether this statement simply affirms a commitment to existing agreements or signals support for additional arms control measures.
October 3-5, 2002: James Kelly, assistant secretary of state for East Asian and Pacific affairs, visits North Korea. The highest-ranking administration official to visit Pyongyang, Kelly reiterates U.S. concerns about North Korea’s nuclear and missile programs, export of missile components, conventional force posture, human rights violations, and humanitarian situation. Kelly informs North Korea that it could improve bilateral relations through a “comprehensive settlement” addressing these issues. No future meetings are announced.
Referring to Kelly’s approach as “high handed and arrogant,” North Korea argues that the U.S. policy “compels the DPRK to take all necessary countermeasures, pursuant to the army-based policy whose validity has been proven.”
October 16, 2002: The United States announces that North Korea admitted to having a clandestine program to enrich uranium for nuclear weapons after James Kelly, assistant secretary of state for East Asian and Pacific affairs, confronted representatives from Pyongyang during an October 3-5 visit. Kelly later explained that the North Korean admission came the day after he informed them that the United States was aware of the program. North Korea has denied several times that it admitted to having this program.
State Department spokesman Richard Boucher states that "North Korea's secret nuclear weapons program is a serious violation of North Korea's commitments under the Agreed Framework as well as under the nuclear Nonproliferation Treaty, its International Atomic Energy Agency safeguards agreement, and the Joint North-South Declaration on the Denuclearization of the Korean Peninsula."
Boucher also says that the United States wants North Korea to comply with its nonproliferation commitments and seeks "a peaceful resolution of this situation."
November 5, 2002: North Korea threatens to end its moratorium on ballistic missile tests if North Korea-Japan normalization talks do not achieve progress.
November 14, 2002: KEDO announces that it is suspending heavy-fuel oil deliveries to North Korea in response to Pyongyang's October 4 acknowledgment that it has a uranium-enrichment program. The last shipment reached North Korea November 18.
November 29, 2002: The IAEA adopts a resolution calling upon North Korea to "clarify" its "reported uranium-enrichment program." North Korea rejects the resolution, saying the IAEA's position is biased in favor of the United States.
December 9, 2002: Spanish and U.S. forces intercept and search a ship carrying a shipment of North Korean Scud missiles and related cargo to Yemen. The United States allows the shipment to be delivered because it lacks the necessary legal authority to seize the cargo. White House Press Secretary Ari Fleischer says that Washington had intelligence that the ship was carrying missiles to the Middle East and was concerned that its ultimate destination might have been Iraq.
December 12, 2002: North Korea sends a letter to the IAEA announcing that it is restarting its one functional reactor and is reopening the other nuclear facilities frozen under the Agreed Framework. The letter requests that the IAEA remove the seals and monitoring equipment from its nuclear facilities. A North Korean spokesman blames the United States for violating the Agreed Framework and says that the purpose of restarting the reactor is to generate electricity-an assertion disputed by U.S. officials.
A November 27 Congressional Research Service report states that the reactor could annually produce enough plutonium for one bomb. The CIA states in a 2002 report to Congress that the spent-fuel rods "contain enough plutonium for several more [nuclear] weapons."
U.S. estimates on North Korea's current nuclear status differ. A State Department official said January 3, 2003 that the U.S. intelligence community believes North Korea already possesses one or two nuclear weapons made from plutonium produced before the negotiation of the Agreed Framework. The CIA publicly estimates that Pyongyang "has produced enough plutonium" for one or two weapons.
December 14, 2002: North Korea states in a letter to the IAEA that the status of its nuclear facilities is a matter between the United States and North Korea and "not pursuant to any agreement" with the IAEA. The letter further declares that North Korea will take unilateral action to remove seals and monitoring cameras if the IAEA does not act.
December 22-24, 2002: North Korea cuts all seals and disrupts IAEA surveillance equipment on its nuclear facilities and materials. An IAEA spokesman says December 26 that North Korea started moving fresh fuel rods into the reactor, suggesting that it might be restarted soon.
December 27, 2002: North Korea orders IAEA inspectors out of the country. They leave on December 31.
January 6, 2003: The IAEA Board of Governors adopts a resolution condemning North Korea's decision to restart its nuclear reactor and resume operation of its related facilities. The resolution "deplores" North Korea's action "in the strongest terms" and calls on Pyongyang to meet "immediately, as a first step" with IAEA officials. It also calls on North Korea to re-establish the seals and monitoring equipment it dismantled, comply fully with agency safeguards, clarify details about its reported uranium-enrichment program, and allow the agency to verify that all North Korea’s nuclear material is "declared and…subject to safeguards."
January 10, 2003: North Korea announces its withdrawal from the nuclear Nonproliferation Treaty (NPT), effective January 11. Although Article X of the NPT requires that a country give three months’ notice in advance of withdrawing, North Korea argues that it has satisfied that requirement because it originally announced its decision to withdraw March 12, 1993, and suspended the decision one day before it was to become legally binding.
January 12, 2003: Choe Jin Su, North Korea’s ambassador to China, signals that Pyongyang might not adhere to its moratorium on testing long-range missiles, saying that Pyongyang believes it “cannot go along with the self-imposed missile moratorium any longer,” according to a January 12 Los Angeles Times article.
February 12, 2003: Responding to North Korea’s rejection of the November 2002 and January 2003 IAEA resolutions, the IAEA Board of Governors adopts a resolution declaring Pyongyang in “further non-compliance” with its obligations under the NPT. The board decides to report the matter to the UN Security Council, in accordance with agency mandates.
February 27, 2003: U.S. officials confirm North Korea has restarted the five-megawatt nuclear reactor that had been frozen by the Agreed Framework.
March 19, 2003: North Korea again signals that it might not adhere to its moratorium on testing long-range missiles, asserting in a March 19 KCNA statement that it has the “sovereign right” to have a “peaceful” missile program. North Korea conducted missile tests February 24 and March 10, but both tests involved short-range missiles that did not violate the moratorium.
March 24, 2003: The United States imposes sanctions on the Changgwang Sinyong Corporation of North Korea for transferring missile technology to Khan Research Laboratories in Pakistan. The laboratory was sanctioned for receiving the items. Philip Reeker, deputy State Department spokesman, said April 1 that the sanctions were imposed only for a “missile-related transfer” and not the transfer of nuclear technology from Pakistan to North Korea.
April 23-25, 2003: The United States, North Korea, and China hold trilateral talks in Beijing. North Korea tells the U.S. delegation that it possesses nuclear weapons, according to Boucher on April 28. This constitutes the first time that Pyongyang has made such an admission.
North Korea also tells the U.S. delegation that it has completed reprocessing the spent nuclear fuel from the five-megawatt reactor frozen under the Agreed Framework, according to Secretary of State Colin Powell during an April 30 hearing before the Senate Appropriations Committee.
Boucher adds that the North Korean delegation told the U.S. officials that Pyongyang “might get rid of all their nuclear programs…[and] stop their missile exports.” Powell states April 28 that North Korea expects “something considerable in return” for this effort.
May 12, 2003
North Korea accuses the United States of violating the spirit of the 1992 Joint North-South Declaration on the Denuclearization of the Korean Peninsula, calling the agreement a “dead document” in a KCNA statement.
July 15, 2003
State Department spokesman Richard Boucher tells reporters that North Korean officials at their UN mission in New York have told U.S. officials that North Korea has completed reprocessing the 8,000 spent fuel rods from its Yongbyon reactor.
August 27-29, 2003
The first round of six-party talks is held in Beijing. The talks achieve no significant breakthroughs.
North Korea proposes a step-by-step solution, calling for the United States to conclude a “non-aggression treaty,” normalize bilateral diplomatic relations, refrain from hindering North Korea’s “economic cooperation” with other countries, complete the reactors promised under the Agreed Framework, resume suspended fuel oil shipments, and increase food aid. Pyongyang states that, in return, it will dismantle its “nuclear facility,” as well as end missile testing and export of missiles and related components. North Korea issues an explicit denial for the first time that it has a uranium-enrichment program.
The North Korean delegation, however, also threatens to test nuclear weapons or “demonstrate the means that they would have to deliver” them, according to a senior State Department official.
September 14, 2003: President George W. Bush agrees to waive the restrictions on U.S. funding to KEDO but only pledges to provide $3.72 million solely for administrative expenses. The United States does not provide any further funding for KEDO after 2003.
October 2, 2003
KCNA reports a statement from a North Korean Foreign Ministry official indicating that North Korea completed reprocessing its 8,000 spent fuel rods and “made a switchover in the use” of the spent fuel “in the direction increasing [sic] its nuclear deterrent force.” The official also states that Pyongyang will continue to produce and reprocess additional spent fuel when deemed necessary.
October 16, 2003
A statement from a North Korean Foreign Ministry official reported by KCNA suggests that Pyongyang may test nuclear weapons, stating that it will “take a measure to open its nuclear deterrent to the public as a physical force” if the United States refuses to change its negotiating stance.
October 19, 2003
President George W. Bush states during a trip to Asia that the United States is willing to provide a written, multilateral guarantee that the United States will not attack North Korea, but makes it clear that a formal nonaggression pact is “off the table.” Powell made a similar statement August 1.
November 6, 2003: North Korean ambassador to the United Kingdom, Ri Yong Ho, tells Reuters that North Korea possesses a workable nuclear device.
November 21, 2003
The KEDO Executive Board announces that it will suspend construction of two light-water nuclear reactors for one year beginning December 1. The Board adds that the project’s future “will be assessed and decided by the Executive Board before the expiration of the suspension period.” Department of State spokesperson Adam Ereli said November 5, however, that Bush administration believes there is “no future for the project.”
January 8, 2004
North Korea allows an unofficial U.S. delegation to visit its nuclear facilities at Yongbyon and displays what it calls its “nuclear deterrent.” North Korean officials allow delegation member Siegfried Hecker—a senior fellow at the Los Alamos National Laboratory—to handle a jar containing what appears to be plutonium metal. North Korean officials claim that it came from reprocessing the spent fuel rods from its five-megawatt reactor.
The delegation also visits the spent fuel cooling pond that had been monitored under the Agreed Framework and observes that the rods have been removed. The North Korean officials tell the delegation that Pyongyang reprocessed all of the spent fuel rods between January and June 2003.
Hecker later tells the Senate Foreign Relations Committee that he does not know for certain that the substance was plutonium and that he could not determine when it was produced.
February 25-28, 2004
A second round of six-party talks takes place in Beijing. Little progress is made, although both sides agree to hold another round of talks before the end of June 2004, as well as a working group meeting to be held beforehand.
South Korea’s deputy foreign minister, Lee Soo-hyuck, issues a proposal—which China and Russia both support—to provide energy assistance to the North in return for a freeze of its nuclear program, along with a promise to dismantle it.
Wang Yi, China’s envoy to the six-party talks, states afterwards that “sharp” differences remain between Washington and Pyongyang. According to the Japanese Foreign Ministry, two specific issues divide North Korea and other participants. The first is that the United States, Japan, and South Korea want all of North Korea’s nuclear programs to be dismantled, but North Korea wishes to be allowed to retain one for “peaceful purposes.” The second is that Washington and the other two governments want Pyongyang to acknowledge that it has a uranium-enrichment program.
June 23-26, 2004: A third round of six-party talks is held in Beijing. The United States presents a detailed proposal for resolving the crisis.
The proposal calls for a two-phase process in which North Korea would receive fuel oil from China, South Korea, and Russia after agreeing to first freeze, then dismantle its nuclear programs. The United States and the other parties to the talks would also draft a multilateral security agreement and begin surveying North Korea’s energy needs. Additionally, Washington would begin bilateral discussions with Pyongyang on the removal of U.S. sanctions. The benefits spelled out in the proposal could be withdrawn if North Korea did not comply.
According to a June 28 North Korean Foreign Ministry statement, North Korea counters by proposing to “refrain from” producing, testing, or transferring nuclear weapons and to freeze “all the facilities related to nuclear weapons and products churned out by their operation.” According to the Foreign Ministry, the length of the freeze depends on “whether reward is made or not.”
November 26, 2004: The KEDO Executive Board announces that it will extend its suspension of the light-water reactor project for another year, beginning December 1.
February 2, 2005: The New York Times and The Washington Post report that Libya received uranium hexafluoride suspected to be of North Korean origin in 2004. Several knowledgeable U.S. and other diplomatic sources later tell Arms Control Today that the evidence indicates, but does not prove, that the material originated in North Korea.
February 10, 2005: North Korea’s Foreign Ministry announces that Pyongyang has “produced nuclear weapons.” This was Pyongyang’s most definitive public claim to date at the time
on the status of its nuclear arsenal.
February 21, 2005: Seoul’s semi-official Yonhap News Agency reports that South Korea’s defense minister, Yoon Kwang-ung, tells a National Assembly Committee that North Korea has reprocessed “only part” of the 8,000 spent fuel rods from the Yongbyon reactor.
March 2, 2005: North Korea’s Foreign Ministry states that Pyongyang is no longer bound by its more than five-year-old moratorium on flight-testing longer-range missiles. Pyongyang, however, does not say it will resume such testing.
Early April, 2005: The United States sends an urgent diplomatic message to allies notifying them of U.S. concerns that North Korea might conduct a nuclear test.
April 9, 2005: North Korea expert Selig Harrison tells reporters that, during a recent meeting, North Korean Vice Foreign Minister Kim Gye Gwan said Pyongyang might give nuclear weapons to terrorists if “the United States drives us into a corner.”
May 11, 2005: North Korea’s Foreign Ministry announces that it has “successfully finished the unloading of 8,000 spent fuel rods” from its Yongbyon reactor. South Korea has verified the reactor shutdown “through various channels,” Foreign Affairs and Trade Ministry official Kim Sook tells the Korean Broadcasting System the same day.
June 2005: Pyongyang refuels its reactor at Yongbyon and begins reprocessing the 8,000 spent fuel rods removed in March, North Korean officials later tell Hecker.
June 29, 2005: The U.S. Treasury Department announces that the United States has frozen the U.S. assets of three North Korean entities “responsible for WMD and missile programs,” as well as barred U.S. citizens and companies from doing business with those entities. Those measures are taken pursuant to Executive Order 13382 issued that day by President George W. Bush.
July 9, 2005: After a meeting between U.S. Assistant Secretary of State for East Asian and Pacific Affairs Christopher Hill and North Korean Vice Foreign Minister Kim Gye Gwan, North Korea announces its return to the six-party talks. According to a KCNA statement, the “U.S. side clarified its official stand to recognize [North Korea] as a sovereign state, not to invade it and hold bilateral talks within the framework of the six-party talks.”
July 13, 2005: During a meeting with an envoy of Chinese President Hu Jintao, North Korean Leader Kim Jong Il reiterates his father’s [Kim Il Sung] apparent dying wish for the denuclearization of the Korean Peninsula, according to KCNA.
July 26, 2005: A new round of six-party talks begins in Beijing. The talks include an unprecedented number of U.S.-North Korean bilateral talks. While North Korea continued to deny that it has a “uranium-based nuclear weapons program,” Pyongyang suggested that it would “clarify” any relevant “credible information or evidence” presented by the United States in that regard.
The participants agree August 7 to recess for several weeks. The talks resume September 13.
September 15, 2005: The Department of the Treasury designates a Macau bank, Banco Delta Asia, as a “primary money laundering concern” under Section 311 of the USA PATRIOT Act, freezing about $25 million in North Korean funds. A department press release states that the bank has provided services to North Korean “government agencies and front companies,” adding that “[e]vidence exists that some of these agencies and front companies are engaged in illicit activities,” such as drug trafficking. The bank also has also circulated North Korean-produced counterfeit U.S. currency, the press release alleges.
September 19, 2005: The participants in the six-party talks conclude a joint statement of principles to guide future negotiations.
According to the statement, North Korea commits “to abandoning all nuclear weapons and existing nuclear programs and returning, at an early date, to the Treaty on the Non-Proliferation of Nuclear Weapons and to IAEA safeguards.” It also calls for the 1992 Joint Declaration of the Denuclearization of the Korean Peninsula, which forbids the two Koreas from possessing uranium-enrichment and plutonium-separation facilities, to be “observed and implemented.” Washington affirms in the statement that it has no intention to attack or invade North Korea.
The statement commits the participants to achieving “the verifiable denuclearization of the Korean Peninsula in a peaceful manner” and says that the parties agree “to take coordinated steps to implement” the agreed-upon obligations and rewards “in a phased manner in line with the principle of ‘commitment for commitment, action for action.’”
The statement says that North Korea “stated that it has the right to peaceful uses of nuclear energy” and that the other parties “expressed their respect and agreed to discuss, at an appropriate time, the subject of the provision” of a light-water nuclear power reactor to Pyongyang. This issue had been controversial during the negotiations and the final agreement was the result of a compromise between Washington and Pyongyang. North Korea insisted that the statement recognize its right to a peaceful nuclear energy program and commit the other participants to provide it with light-water reactors while the United States argued that North Korea should not receive any nuclear reactors.
September 20, 2005: North Korea’s Foreign Ministry states that it is “essential” for the United States to provide light-water reactors to Pyongyang “as early as possible,” adding that Washington “should not even dream” that North Korea will dismantle its “nuclear deterrent” before receiving the reactors. However, a speech from North Korean Vice Foreign Minister Choe Su Hon two days later appears to back away from this formulation.
October 20, 2005: Democratic New Mexico Governor Bill Richardson, who visited North Korea earlier in the month, says North Korean officials told him they had reprocessed the 8,000 spent fuel rods from the Yongbyon reactor, the Associated Press reports.
October 21, 2005: The Treasury Department announces that it has sanctioned eight North Korean entities pursuant to Executive Order 13382 for their unspecified “involvement” in the proliferation of nuclear, chemical, or biological weapons or related delivery vehicles. The action freezes the entities’ U.S. assets and prohibits transactions between these entities and any U.S. citizens or companies. The department had similarly designated those entities’ parent companies in June.
November 9-11, 2005: The fifth round of the six-party talks begins in Beijing.
South Korea and Japan present concrete plans for implementing the September statement. Both countries propose that the participants separate outstanding issues into three categories: the dismantlement of Pyongyang’s nuclear program, provision of economic and energy assistance to North Korea, and Pyongyang’s bilateral issues with Washington and Tokyo.
Disagreements between Washington and Pyongyang continue to block progress. The North Korean delegation focuses almost exclusively on the funds frozen by the September Banco Delta Asia designation.
December 19, 2005: North Korea announces that it will “pursue” the construction of larger “graphite-moderated reactors,” an apparent reference to the two reactors whose construction had been frozen under the Agreed Framework in Pyongyang’s most definitive public statement on the matter.
March 7, 2006: Officials from the U.S. Treasury Department brief North Korea’s deputy director-general for North America, Li Gun, as well as other North Korean officials about the U.S. actions taken with respect to Banco Delta Asia. Li tells reporters afterward that his delegation proposed several methods for resolving U.S. concerns, South Korea’s semi-official Yonhap News Agency reports. Among them was a suggestion to form a joint U.S.-North Korean consultative committee of experts that would discuss such issues as counterfeiting and money laundering.
March 17, 2006: Department of State spokesperson Adam Ereli indicates during a press briefing that issues related to North Korea’s financial system could potentially be discussed in the six-party talks.
March 30, 2006: The Treasury Department announces that it has imposed penalties on a Swiss company, along with one of its owners, for procuring “goods with weapons-related applications” for North Korea.
April 13, 2006: North Korean Vice Foreign Minister Kim Gye Gwan tells reporters that Pyongyang would return to the talks if the United States lifted the freeze of Banco Delta Asia’s funds, which total approximately $25 million.
June 1, 2006: The KEDO Executive Board announces that it has formally terminated its project to build two light-water nuclear reactors in North Korea.
The board says its decision was based on the “continued and extended failure” of North Korea to comply with its relevant obligations under the 1994 Agreed Framework.
According to South Korea’s Unification Ministry, KEDO’s executive board adopted a resolution the previous day saying that Seoul is to “cover the costs arising from the liquidation process,” of the KEDO assets, such as resolving compensation claims from subcontractors. In return, the government-owned Korea Electric Power Corp., the prime contractor for the reactor project, would gain ownership over reactor “equipment and materials” located outside of North Korea. The fate of assets remaining in North Korea, such as vehicles and construction equipment, is unclear.
July 4-5, 2006: North Korea test fires seven ballistic missiles, including its longest-range missile, the Taepo Dong-2. The other six tests include a combination of short- and medium-range Scud-C and Nodong ballistic missiles, launched from the Kittaraeyong test site. Although the tests of the six short-range missiles appear to be successful, the Taepo Dong-2 fails less than a minute after launch.
A July 4 State Department press statement describes the launches as a “provocative act” that violated North Korea’s voluntary moratorium on flight-testing longer-range missiles, which Pyongyang had observed since September 1999.
Japan and South Korea punish North Korea for conducting the tests, with Tokyo imposing sanctions on Pyongyang and Seoul halting food and fertilizer assistance.
July 15, 2006: The UN Security Council adopts Resolution 1695 condemning North Korea’s missile launches. The resolution calls on Pyongyang to return to the six-party talks and “demands” that the country suspend its ballistic-missile activities and re-establish its flight-testing moratorium.
The resolution also requires states to prevent missiles and related “items, materials, goods and technology” from being transferred to North Korea’s missile or weapons of mass destruction programs. In addition, it requires countries to prevent the procurement of such items from Pyongyang and the transfer of any “financial resources in relation to” North Korea’s weapons programs.
North Korea’s Foreign Ministry states the next day that Pyongyang will “not be bound” by the resolution.
September 19, 2006: Japan and Australia announce that they have adopted sanctions targeting multiple foreign entities tied to North Korea’s ballistic missile and nuclear, chemical, and biological weapons programs in response to resolution 1695.
The two countries each punish the same 12 organizations, as well as a Swiss citizen. All entities are already subject to similar U.S. sanctions. Japan also sanctions three additional institutions.
October 3, 2006: North Korea’s Foreign Ministry issues a statement asserting that Pyongyang “will in the future conduct a nuclear test under the condition where safety is firmly guaranteed.” Apparently signaling a degree of restraint, the statement also says that North Korea will refrain from the first-use of nuclear weapons, “strictly prohibit any …nuclear transfer,” and “do its utmost to realize the denuclearization of the [Korean] peninsula.”
October 9, 2006: North Korea conducts an underground nuclear test near the village of P’unggye. Most early analyses of the test based on seismic data collected by South Korean, Japanese, and U.S. institutes estimates the yield to be below one kiloton. Russian estimates differed significantly, and Foreign Minister Sergei Ivanov said Oct. 10 that the estimated yield was between 5 and 15 kilotons.
October 11, 2006: North Korea’s Foreign Ministry states that its “nuclear test was entirely attributable to the US nuclear threat, sanctions and pressure,” adding that North Korea “was compelled to substantially prove its possession of nukes to protect its sovereignty.” The statement also indicates that North Korea might conduct further nuclear tests if the United States “increases pressure” on the country.
However, the Foreign Ministry also says that North Korea remains committed to implementing the September 2005 joint statement, arguing that the test “constitutes a positive measure for its implementation.” Additionally, Pyongyang “still remains unchanged in its will to denuclearize the peninsula through dialogue and negotiations,” the Foreign Ministry statement says, adding that the “denuclearization of the entire peninsula was President Kim Il Sung’s last instruction and an ultimate goal” of North Korea.
October 14, 2006: The UN Security Council adopts Resolution 1718. The measure demands that North Korea refrain from further nuclear tests and calls on Pyongyang to return to the six-party talks and abandon its nuclear weapons. It also imposes additional sanctions on commerce with Pyongyang, widening the range of prohibited transactions beyond those banned under Resolution 1695.
November 28-December 1, 2006: The Chinese, North Korean, South Korean, and U.S. envoys to the six-party talks hold consultations in Beijing to discuss resuming the fifth round of talks. During the consultations, North Korean envoy Kim Gye Gwan states that North Korea is ready to implement the September 19, 2005 joint statement and abandon its nuclear program, but would not do so “unilaterally.”
December 18-22, 2006: The fifth round of six-party talks resumes in Beijing. The United States presents a multistage denuclearization plan, but the talks make no progress towards implementing the September 19, 2005 joint statement—in part due to continued disagreements regarding the North Korean funds frozen by the United States in Banco Delta Asia. The parties agree to meet again “at the earliest opportunity.”
February 8-13, 2007: The six-party talks concludes its fifth round with an agreed “action plan” of initial steps to implement the September 19, 2005 joint statement on North Korea’s denuclearization.
According to the action plan, North Korea is to halt the operation of its nuclear facilities at Yongbyon during a 60-day initial phase in return for an initial shipment of 50,000 tons of heavy-fuel oil.
The action plan also establishes five working groups to “discuss and formulate specific plans” regarding: economic and energy cooperation; denuclearization; implementation of a “Northeast Asia Peace and Security Mechanism;” North Korean relations with the United States; and North Korean relations with Japan.
The statement indicates that, following the shutdown of North Korea’s nuclear facilities at Yongbyon, Pyongyang is to provide a complete declaration of all of its nuclear programs and disable all of its existing nuclear facilities in return for an additional 950,000 tons of heavy-fuel oil or its equivalent.
In addition to helping to provide energy aid to North Korea, the United States agrees to begin the process of removing Pyongyang from its list of state sponsors of terrorism and to stop the application of the Trading with the Enemy Act toward North Korea.
March 13-14, 2007: IAEA Director-General Mohamed ElBaradei visits North Korea and meets with three officials, including the head of the North Korean General Department of Atomic Energy, Ri Je Son. During the meetings, ElBaradei invites North Korea to return to the IAEA as a member state and discusses the agency’s monitoring and verification role during the implementation of a February 13 six-party talks agreement.
March 19-22, 2007: The sixth round of six-party talks begins in Beijing. The discussions are suspended when North Korean negotiators fly home after four days, explaining that they will not participate until the United States transfers $25 million in frozen North Korean funds held in Banco Delta Asia.
On March 19, Treasury Department Deputy Assistant Secretary for Terrorist Financing and Financial Crimes Daniel Glaser announces that the two countries had “reached an understanding” regarding the frozen funds, with Washington accepting a North Korean proposal that the funds would be transferred to a North Korean account in the Bank of China in Beijing. North Korea also pledges that the funds “will be used solely for the betterment of the North Korean people, including for humanitarian and educational purposes.”
April 10, 2007: The United States agrees to unfreeze the $25 million in North Korean funds frozen in its Banco Delta Asia account. U.S. officials insist, meanwhile, that North Korea, “live up to the assurances that these funds will be used for the betterment of the North Korean people and for humanitarian purposes.”
June 25, 2007: A North Korean Foreign Ministry spokesman confirms that the Banco Delta Asia funds were transferred to Pyongyang and that North Korea would begin shutting down its Yongbyon nuclear facilities. An IAEA delegation led by Deputy Director-General for safeguards Ollie Heinonen arrives in Pyongyang the following day to discuss the verification procedures for the shutdown.
July 16, 2007: The IAEA confirms the shutdown of the Yongbyon nuclear facilities.
July 18-20, 2007: The six-party talks reconvenes its sixth round in Beijing. The meeting concludes with a joint communiqué indicating that the five working groups will all meet by the end of August in preparation for another round of plenary talks in September.
September 6, 2007: Israel carries out an air-strike destroying a Syrian facility of an undetermined purpose. Early press reports quoting unnamed U.S. officials suggest that the target of the airstrike was a nuclear facility under construction with North Korean assistance. Days after the strike, Syrian officials deny that the facility was nuclear related, while Israeli and U.S. officials only confirm that an air-strike was carried out. In the following months, Assistant Secretary of State Christopher Hill states on several occasions that he has raised the issue of the Syrian facility with North Korea. U.S. officials later indicate that the facility was believed to have been a nearly completed nuclear reactor modeled on the North Korean nuclear reactor at Yongbyon.
September 11-14, 2007: A team of Chinese, Russian, and U.S. experts visit North Korea to examine the Yongbyon nuclear facilities to determine the steps necessary to disable them. The experts team agrees on a draft disablement plan with North Korean officials which is to be considered by the next plenary meeting of the six-party talks.
September 27-October 3, 2007: The sixth round of six-party talks meets to discuss how to proceed with the second phase of the February 13 agreement. On October 3, the participants issue a joint statement in which North Korea agrees that, by December 31, it would provide a “complete and correct declaration of all its nuclear programs – including clarification regarding the uranium issue,” and disable its Yongbyon nuclear facilities. Pyongyang also agrees to disable all other nuclear facilities subject to the September 2005 joint statement and not to transfer nuclear material or technology abroad.
In return, the six-parties agree that North Korea would receive the remaining 900,000 tons of heavy-fuel oil or its equivalent pledged in the February 13 agreement.
The United States also agrees that it will fulfill its commitments to begin removing North Korea from its list of state sponsors of terrorism and “advance the process of terminating the application of the Trading with the Enemy Act” toward North Korea “in parallel with” North Korea’s denuclearization actions.
October 2-4, 2007: South Korean President Roh Moo-hyun travels to Pyongyang to meet with North Korean leader Kim Jong Il to discuss prospects for reconciliation and economic cooperation. It is the second time in history that such summit-level discussions have been held.
The summit concludes with a an eight-point joint declaration in which both sides agree to take steps toward reunification, ease military tensions, expand meetings of separated families, and engage in social and cultural exchanges. The declaration also expresses a “shared understanding” by the two countries “on the need for ending the current armistice mechanism and building a permanent peace mechanism.”
November 5, 2007: A team of U.S. experts arrives in North Korea to begin leading the disablement of the Yongbyon nuclear facilities. The disablement process consists of 11 agreed steps to be completed by the December 31 deadline stipulated in the October 3 agreement. Funding for the disablement process is provided by the State Department’s Nonproliferation and Disarmament Fund (NDF), which is ordinarily reserved for short-term emergency nonproliferation needs.
December 19, 2007: Grand National Party candidate Lee Myung-bak is elected president of South Korea, ushering in the first conservative government in Seoul in 10 years. During his campaign, Lee pledged to review the “Sunshine policy” of short-term reconciliation with North Korea adopted by his two predecessors, instead favoring the application of greater pressure on Pyongyang to denuclearize.
December 21, 2007: The Washington Post reports that U.S. technical teams discovered traces of enriched uranium on aluminum tubes North Korea shared with U.S. officials in November. According to the report, it is unclear whether the contamination originated in North Korea as a result of uranium enrichment carried out by Pyongyang, or if North Korea imported materials which were contaminated abroad and placed these materials in close proximity to the aluminum tubes.
January 2, 2008: Following a December 31, 2007 deadline for North Korea to provide a complete and correct declaration on its nuclear programs and disable its Yongbyon nuclear facilities, State Department spokesman Sean McCormack indicates that “some technical questions about the cooling of the fuel rods” was the reason behind the failure to meet the year-end deadline for disablement. He added that Washington would continue to press Pyongyang for its nuclear declaration.
January 4, 2008: KCNA releases a North Korean Foreign Ministry statement declaring that North Korea “worked out a report on the nuclear declaration in November last year and notified the U.S. side of its contents.” The statement also accuses the other parties of falling behind on their commitments under an October 2007 agreement, including delays in the delivery of heavy-fuel oil to North Korea. Pyongyang indicated that it would slow down the disablement process in response to delays in the delivery of energy assistance.

He informs the committee that while the tubes did not work with one of these systems, the U.S. government accepts that the tubes were currently being used for a second conventional weapons system.
Hill also requests from Congress a limited waiver of 1994 Glenn amendment sanctions imposed on North Korea following its nuclear test in 2006.
