The Agreed Framework between the United States of America and the Democratic People's Republic of Korea was signed on October 21, 1994, between North Korea (DPRK) and the United States. The objective of the agreement was the freezing and replacement of North Korea's indigenous nuclear power plant program with more nuclear proliferation resistant light water reactor power plants, and the step-by-step normalization of relations between the U.S. and the DPRK. Implementation of the agreement was troubled from the start, but its key elements were being implemented until it effectively broke down in 2003.
On 12 December 1985, North Korea became a party to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). On 10 April 1992 its NPT safeguards agreement entered into force. In May 1992, North Korea submitted its initial report to the IAEA under that agreement, and International Atomic Energy Agency (IAEA) inspections began. Shortly thereafter inconsistencies emerged between the North Korea initial declaration and the Agency's findings, centring on a mismatch between declared plutonium product and nuclear waste solutions and the results of the Agency's analysis. The latter suggested that undeclared plutonium existed in North Korea. In order to find answers to the inconsistencies detected and to determine the completeness and correctness of the initial declaration provided, the IAEA requested access to additional information and to two sites which seemed to be related to the storage of nuclear waste. The DPRK refused access to the sites, and on 12 March 1993, North Korea announced its decision to withdraw from the NPT.
On 1 April 1993, the IAEA concluded that North Korea was in non-compliance with its Safeguards Agreement, and referred this to the UN Security Council. Following UN Security Council resolution 825, which called upon the DPRK to reconsider its decision to withdraw from the Nuclear Non-Proliferation Treaty and allow weapons inspectors from the International Atomic Energy Agency (IAEA) into the country, North Korea "suspended the effectuation" of that withdrawal in June 1993.
