The Gao Gang Affair, also known as the Gao-Rao Affair, was Gao Gang's attempt to displace Liu Shaoqi and Zhou Enlai from key posts in the government, and to increase his own standing within the Chinese Communist Party (CCP). Because of Mao Zedong's apparent displeasure with the previous failures of Liu and Zhou, Gao assumed that he had Mao's approval for such a move and began to approach senior cadres in the summer of 1953 asking for support. Gao leaked a list of Politburo members drafted by An Ziwen, the vice chief of the CCP Personnel Department, making Mao suspicious of Gao's intentions before the upcoming CCP Eighth Congress. While sources disagree on the reason for An's creation of the list, Gao mentioned and referred to the confidential document during meetings, believing that it was Liu's ploy to leverage his own position in the party. Gao had spoken to several other cadres about the matter including Chen Yun and Deng Xiaoping, who saw Gao's plan as an effort to overthrow Liu Shaoqi entirely. Deng revealed a more detailed account of Gao's "underground activities" in 1980, stating that "he tried to win me over and had formal negotiations with me in which he said that Comrade Liu Shaoqi was immature. He was trying to persuade me to join in his effort to topple Comrade Liu Shaoqi." When Chen Yun and Deng Xiaoping officially informed Mao of Gao's activities, the chairman declared them out of order, and efforts were undertaken to address the perceived threat to party unity. Gao killed himself August 1954.
