On 27 July 1953, United Nations Command, the Korean People's Army, and the Chinese People's Volunteers signed the Korean Armistice Agreement, ending open hostilities. The agreement established the Military Armistice Commission (MAC), consisting of representatives of the signatories, to supervise the implementation of the armistice terms, and the Neutral Nations Supervisory Commission (NNSC), composed of nations that did not participate in the conflict, to monitor the armistice's restrictions on the parties' reinforcing or rearming themselves. In 1975, the UN General Assembly adopted resolution 3390 (XXX), which expresses hope that UNC is to be dissolved on 1 January 1976. However, UNC was not dissolved by the United States.
