In February, President Nixon visited China, met with President Mao Zedong and held talks with Premier Zhou Enlai. The two sides signed a Sino-US joint communique in Shanghai. At the same time, on the issue of Taiwan Province Province, which has long hindered the improvement of bilateral relations, the United States said: "The United States recognizes that all China people on both sides of the Taiwan Province Province believe that there is only one China, and Taiwan Province Province is a part of China. The US government does not object to this position. " The publication of the Sino-US Joint Communiqué marked the end of more than 20 years of hostility between China and the United States and the beginning of normalization of relations between the two countries. At the same time, because of President Nixon's visit to China, the American government avoided Japan, which caused great shock to the Japanese ruling and opposition parties. Therefore, it also contributed to the visit of Japanese Prime Minister tanaka kakuei to China in September 1972. The two sides signed the Sino-Japanese Joint Statement, which severed the "diplomatic relations" between Japan and the authorities of Taiwan Province Province and normalized the diplomatic relations between China and Japan. Therefore, it can be said that 1972 President Nixon's visit to China was a very powerful event in the world at that time, and China ushered in the third climax of the establishment of diplomatic relations.
