From June 1951 to July 1953, China’ policy on the Korean War armistice negotiations undertook several major changes, which were not only reactions to the adversary, but also a consequence of resolving differences and coordinating positions among China, the Soviet Union and North Korea. The interaction between China and its allies sometimes had a more profound impact upon the process of armistice negotiations. The armistice on the Korean Peninsula was a result of both the struggle between the warring parties as well as the intra-alliance decision-making structure and contradictions in the two camps. Understanding the internal problems of the two alliances is therefore as important as studying the military situation and power balance on the battlefield.
