United Nations forces met with North Korean and Chinese officials at Panmunjeom from 1951 to 1953 for truce talks. The talks dragged on for many months. The main point of contention during the talks was the question surrounding the prisoners of war. Moreover, South Korea was uncompromising in its demand for a unified state. On June 8, 1953, an agreement to the POW problem was reached.

Those prisoners who refused to return to their countries were allowed to live under a neutral supervising commission for three months. At the end of this period, those who still refused repatriation would be released. Among those who refused repatriation were 21 American and one British POWs, all but two of whom chose to defect to the People's Republic of China.
