China's foreign talks at the Paris Peace Conference did not fail. At that time, Japan thought it should inherit Ji Jiao's rights and interests, because Japan sent troops to lay the Shandong-German railway, and the China government signed Article 21, so China must admit this. Gu Weijun, a famous diplomat, demonstrated this with his profound research on international law. ?
Gu Weijun refuted the Japanese demands one by one. He thinks that the content of "Article 2 1" should not count, because according to the principle of force coercion in international law, the validity of the treaty is still in doubt; In addition, there is the principle of rebus sic stantibus in international law. China did not take part in World War I before, but later declared war on Germany, so the treaty became invalid. According to the historical data found, Gu Weijun did not impress the participants with the rumor that "Shandong is the Jerusalem of China", but refuted the Japanese on the basis of solid international law. ?
However, although China had the upper hand on this issue, influenced by the complicated international political situation at that time, Japan adopted various other ways. At the same time, there are some factional struggles within the China government. Japan finally got some benefits from Germany in Shandong. Gu Weijun said that after the news was published in the newspaper, it finally triggered a vigorous May 4th Movement, and the China delegation finally refused to sign the peace treaty.
Extended data
When the Paris Peace Conference decided not to return Qingdao to China, the manuscripts received by newspapers were published in time, which ignited the anger of the people all over the country, especially young students, and then the vigorous May 4th Movement broke out. Under the great pressure of the people, the Beiyang government delegation did not sign the peace treaty.
The Paris Peace Conference thoroughly exposed the ferocious face of imperialism. The unreasonable decision of the Paris Peace Conference on the Shandong issue has greatly angered the people of China and shattered the imperialist fantasy of the people of China.
