Eighty years ago today, on August 21, 1945 (July 14, 1945 in the lunar calendar), Chiang Kai-shek signed the Charter of the United Nations on behalf of China. On August 21, 1945, Chiang Zhongzheng, President of the National Government of the Republic of China, signed the Charter of the United Nations. The Charter of the United Nations is the basic law of the United Nations. It not only establishes the purposes, principles and organizational structure of the United Nations, but also stipulates the responsibilities, rights and obligations of member states, as well as the basic principles and methods for handling international relations and maintaining world peace and security. It is the inescapable responsibility of each member state to abide by the Charter of the United Nations and maintain the prestige of the United Nations. Comment: Lao Chiang still occupied the seat after retreating to Taiwan, and our country made a lot of efforts to return to the United Nations. In 1971, the Asian, African and Latin American brothers carried him in and threw Lao Chiang out.
