The fall of Chinese anti-Japanese war in 1944 stimulated the changes of American Pacific strategy and the deterioration of
Sino-American relations, which greatly caused Jiang Jieshi's underestimate of Russia's future role in China and limited him to conduct the necessary diplomatic initiatives towards USSR. Then came the Yalta Agreement in February of 1945. After that, Chinese diplomatic efforts were still focusing and trying to " invite" America to mediate the
Sino-Russian relations and involve the future Sine-Russian talks. However, due to the consideration of the Russian power to pursue its interests in North-Eastern Asia, the need of Russia to join the war against Japan and the lack of effective resources to confront Russian, American government not only declined Chinese invitation, but also helped Russia to force China to send its delegation to Moscow for the direct talk with Stalin. American declination doesn't mean that Chinese diplomatic efforts did not work at all. In fact, Chinese continuous invitation eventually made the American government to stand out to help Chinese national government to resist Russian demands in China, which became one of the origins of the outbreak of the Chinese civil war and the Cold War in Asia.
