Abstract: In 1935, Chiang Kai-shek and Wang Jingwei got Germany to mediat the Sino-Japanese conflict, which is not an attempt to take refuge in Germany and Japan's anti-Communist traitorous conspiracy, nor does it sell out national and State interests. Chiang Kai-shek's real objective is, through Germany's mediation to stop Japan to get further expansion of northern China incident, in order to avoid an all-out war, and both sides "mutually assured destruction". In addition, he also wanted to win time for China to prepare Sino-Japanese war. At this time, Chiang Kai-shek was preparing to resist Japan with Russia and it is impossible to establish anti-Soviet front with Japan. Nanjing national Government's policy toward Japan took some major changes, shifting from compromise to the determined resistance, and Chiang Kai-shek decided to end Germany's mediation.
