North and South Korea agree to establish a nuclear-weapons-free zone on the Korean Peninsula. North Korea will withdraw its demand that joint US-South Korean Team Spirit military exercises be ended permanently. In return, South Korea will announce that it is willing to cancel the joint Team Spirit military exercise with the United States scheduled for 1992. South Korea will also withdraw its demand that North Korea sign the IAEA safeguards agreement by 31 January 1992. North Korea is expected to later make a statement committing itself to signing the safeguards agreement.

The nuclear-weapons-free zone agreement allows North and South Korea to use nuclear energy for peaceful purposes only and prohibits the testing, manufacture, production, acceptance, possession, storing or deployment of nuclear weapons on the Korean Peninsula. Furthermore, it prohibits construction of nuclear fuel reprocessing and uranium enrichment facilities. The agreement, expected to be signed by the Korean Prime Ministers in a meeting in February 1992, will establish the Joint Nuclear Control Committee (JNCC). The JNCC’s function will be to conduct talks detailing the implementation of nuclear facility inspections to verify the absence of nuclear weapons. The documents establishing the JNCC’s role must be signed by 18 March 1993.
