 The IAEA was not satisfied that North Korea had fully disclosed its plutonium production and requested access to certain facilities.Due to lack of progress in the negotiations, and the DPRK's refusal to allow inspection of two suspected nuclear waste sites, North Korea notified the IAEA on 12 March 1993 concerning its intention to withdraw from the Non-Proliferation Treaty.The Board of Governors at the IAEA later notified the Security Council that North Korea was not in compliance with its obligations under the Joint Agreement between the DPRK and the IAEA.
