China has become the one of five powers in the world after WWII. But her diplomacy tact cannot be used under the limits of other powers, especially Russia and the United States. On the internal affairs, China was under the heart of domestic war. Wang Shih-chieh signed after his inauguration of Foreign Minister of China. But Wang was criticized because of Russia’s violation of the treaty. The treaty cannot be refused by China in the situation of that time, however, and to sign the treaty has been the policy. It is unfair that to fault Wang’s responsibility for the treaty.
