The November 2010 article “Can Washington and Seoul Try Dealing With Pyongyang for a Change?” by Leon V. Sigal said that a 2000 summit accord between North and South Korea had committed North Korea to abide by the Northern Limit Line in the West (Yellow) Sea until permanent borders were drawn. That provision actually was part of a protocol to the 1991 North-South Agreement on Reconciliation, Non-Aggression, Cooperation and Exchange. On January 29, 2009, after South Korean President Lee Myung-bak backed away from both the 2007 and 2000 North-South summit agreements, North Korea abrogated the 1991 provision.
