In the spring of 1973, according to Mao Zedong's opinion, "Deng Xiaoping formally participated in the work of the State Council's business group and participated in external activities as deputy prime minister." In December of the same year, according to Mao Zedong's proposal, Deng Xiaoping was appointed as a member of the Political Bureau of the Central Committee and a member of the Central Military Commission. In 1974, Deng Xiaoping attended the Sixth Special Session of the United Nations and systematically elaborated on China's foreign policy, attracting worldwide attention. When preparing for the Fourth National People's Congress, Mao Zedong commented that Deng Xiaoping had "rare talents and strong political ideas" and was determined to give him greater responsibilities. Mao Zedong and Zhou Enlai were seriously ill, and Deng Xiaoping was elected as Vice Chairman of the CPC Central Committee, Vice Premier of the State Council, Vice Chairman of the Central Military Commission and Chief of General Staff of the Chinese People's Liberation Army, presiding over the daily work of the Party Central Committee, the country and the military. Deng Xiaoping acted vigorously and resolutely, turned the tide, presided over comprehensive rectification, and achieved remarkable results.
