日本占据中国东北后,其陆、海军在“北进”与“南进”政策有过长时间争执。由于诺门坎战役的失利,苏德签订《互不侵犯条约》,日本在军事与外交上的双重失败,使其陆军丧失发言权。而南洋战略资源的诱惑、日本与英美战略利益的冲突,最终导致日本南进政策的确立。 After Japan occupied the northeast of China, its land and naval forces had a long dispute over the policy of “moving north” and “moving south”. As a result of the defeat of the Norsemendhan campaign, Sudan signed the Treaty of Non-Aggression, and Japan’s double defeat in military and diplomacy made its army lose its say. The temptation of Nanyang strategic resources and the conflict between Japan and the strategic interests of the United States and Britain eventually led to the establishment of Japan’s southbound policy.
