On this day, 67 years ago, July 31, 1958 (June 15, 1958 in the lunar calendar), Khrushchev's secret visit to China ended in discord. At the end of the talks, the two parties signed a joint communiqué. On July 31, 1958, Khrushchev, First Secretary of the Central Committee of the Communist Party of the Soviet Union, came to China for a visit. During the visit, Chairman Mao Zedong of the Central Committee of the Communist Party of China and other leaders discussed with Khrushchev the international situation and Sino-Soviet relations and other issues, and issued the "Communique on the Talks between Mao Zedong and Khrushchev." During the talks, Mao Zedong rejected the Soviet side's recent proposal to establish a joint fleet and a long-wave radio station. Khrushchev denied that the idea of establishing a joint fleet was the opinion of the leaders of the Communist Party of the Soviet Union, saying that Ambassador Eugene did not understand military affairs and did not convey it clearly. They only raised the issue of jointly studying the fleet. Prior to this, in April of the same year, Soviet Defense Minister Malinowski wrote a letter to China Defense Minister Peng Dehuai, proposing to establish a long-wave radio station in China, with the Soviet Union bearing most of the expenses and China bearing part of the expenses. In June, the Central Committee of the Communist Party of China replied: All expenses will be borne by China. Can be used jointly, but the ownership belongs to China. Later, the Soviet side proposed that all the expenses would be borne by the Soviet side, but this matter failed. In July, Eugene, Soviet Ambassador to China, talked with Liu Shaoqi, Vice Chairman of the Central Committee of the Communist Party of China, and then with Mao Zedong about the establishment of the Sino-Soviet Joint Fleet. Mao Zedong pointedly pointed out that this is a political issue. You want to extend Russian nationalism to the coast of China to control us. He rejected this request, which undermined China's independent sovereignty. He asked Ambassador Eugene to tell Khrushchev truthfully what he said.
