鸠山内阁时期中日、苏日关系比较研究

鸠山内阁时期，同属社会主义阵营的中苏两国都积极主张与日恢复邦交，苏日两国很快实现，而中日两国仍停留于民间交往。其原因是复杂的，文章着重从三个方面分析：1、在鸠山内阁外交战略中，日苏关系先于日中关系；2、中苏两国对日外交方式不同，苏联选择政府间的非正式外交方式，中国选择非政府间的民间交往方式；3、中苏两国对解决日俘、渔业等问题的认识不同，苏联将其视为邦交的资本，中国将其视为邦交的前提。

A Comparative Study on Sino-Japanese Relations and Russo- Japanese Relations in the Period of Hatoyama Cabinet

In the period of Hatoyama cabinet, China and USSR, big socialist powers, both advocated to resume the diplomatic relations with Japan. Russo-Japanese relations normalized, but Sino-Japanese relations were still limited in unofficial exchanges. This dissertation tries to explain the differences between Russo-Japanese relations and Sino-Japanese relations from three aspects: first, Russo-Japanese relations were superior to Sino-Japanese relations in the diplomatic strategy of Hatoyama cabinet; second, Chinese Japan-policy was different from USSR's, in detail, USSR adopted intergovernmental informal style of diplomacy while China pursued unofficial exchanges with Japan; third, China and USSR had different understanding of diplomatic issues, such as Japanese prisoners, fishery and so on. USSR regarded these issues as diplomatic capital,but China regarded these issues as the prerequisite of the normalization of diplomatic relations.
