Outline of Final Research Achievements

This research program reexamines the historical process in which the separate peace treaty with Japan was concluded in 1951, criticizing previous researches which emphasize the role of the Western bloc in a series of events. Instead, the program focuses on strategies of the Eastern Communist bloc, particularly the Sino-Soviet alliance’s struggle for overall peace treaty with Japan from 1949 to 1954. The conclusion can be separated into three aspects. First, the Sino-Soviet alliance’s policy toward Japan was composed of two dimensions: the formal diplomacy of both governments and informal strategies of both communist parties. Second, while retaining defensive attitudes to Japan’s problems in the diplomatic arena, the alliance intensified parties’ belligerent stance by urging the Japanese Communist Party to radicalize its revolutionary formula. Third, this dual course decayed by 1953 when the Korean War ended and their formal diplomacy prevailed over informal belligerent strategies.

Academic Significance and Societal Importance of the Research Achievements

当該研究の学術的意義は主に二つある。①戦後日本外交の出発点を多元的に再考すること。西側世界の視点から論じられることの多かったこの問題を旧東側世界の視点から再考した。②冷戦史研究への貢献。マルチ・アーカイバルな手法で中ソ同盟の対日戦略を分析した研究は世界的にも希有である。社会的意義も二点ある。①当該研究の研究対象は現在日本が周辺諸国との間に抱える外交問題の起源に位置する。特に平和条約未締結の日ロ間に生じる外交問題の多くが当該研究の分析対象と深く関わりをもつため、その史的過程を詳細に実証することは喫緊の課題でもある。②研究成果の国際的発信をめざし、中国語による研究報告・学術論文発表に努めた。
