On 74 years ago today, September 4, 1951 (August 4, 1951 in the lunar calendar), the United States manipulated the signing of the Peace Treaty with Japan. On September 4, 1951, in accordance with the Joint Declaration of the United Nations, the Cairo Declaration, the Potsdam Proclamation and other relevant international agreements, after the end of the Second World War, the warring allies against Japan should conclude a comprehensive peace treaty with Japan, and Through the peace treaty, Japan became a democratic and peaceful country. However, the United States betrayed its trust and unilaterally decided to convene a peace conference with Japan when it suffered a disastrous defeat in the war of aggression against North Korea. On September 4, 1951, under the control of the United States, a Peace Conference with Japan was held in San Francisco to exclude the participation of the People's Republic of China and others, and a separate peace treaty with Japan was signed. On the 18th of the same month, the China government issued a solemn statement refusing to recognize the peace treaty. In September 1972, Japanese Prime Minister Kakuei Tanaka visited China, and China and Japan issued a joint statement, which ended the abnormal state between the two countries and normalized diplomatic relations. On August 12, 1978, the two countries signed the China-Japan Treaty of Peace and Friendship. The Soviet Union and Japan issued a joint declaration in October 1956, announcing the end of the state of war and the restoration of diplomatic relations.
