This research focuses on the period when North Korea had the best amicable relationship with China on the background of Sino-Soviet Dispute in the early and middle 1960s. This research aims to rearrange historical facts,based on the following primary materials of Sino-North Korea Relations in the Cold War Period: (1) memoirs and annals the Chinese leadership, (2)China’s diplomatic documents, (3) Russia’s documents found in Woodrow Wilson Center, and (4) materials of East Germany compiled by Korean Institute of National Unification. The immediate cause of the close relations between North Korea and China was the struggle against the Soviet Union and Khrushchev, that is to say Modern Revisionism. There are two interesting points about this. One is that North Korea was active in anti-Soviet, anti-Khrushchevian and anti-Revisionist activities; those activities were more independent more than ones analyzed by previous studies. The other is that North Korea developed its independent doctrine under militarily and economically difficult situations due to a breach in relations with Soviet Union. Based on these historical facts, this research examined Sino-North Korea Relations empirically at the three levels ‘the two countries’ joint ideological struggle against revisionism’,‘national interests in security and economic cooperation of the two countries’, and ‘North Korea’s independent doctrine in national defense and the history of the revolution.’
