Soviet Ambassador to the United Nations Jacob Malik first proposed a cease-fire in 1951, and the first negotiations began in July of that year at Kaesong. However, talks broke down in 1952 over the issue of how to deal with prisoners of war. Meanwhile, hostilities continued. It wasn’t until April of 1953 that the issue was resolved and an agreement was reached and signed in July. Though South Korea refused to sign, fighting ended soon after.
