The document discusses the history of communism in China under Mao Zedong and Deng Xiaoping. It summarizes that Mao established communist rule after defeating the Nationalists in 1949, but his Great Leap Forward and Cultural Revolution caused widespread famine and death. Deng introduced economic reforms in the late 1970s, opening China to foreign trade and investment while maintaining one-party political control. However, the Tiananmen Square protests in 1989 showed the Communist leadership would not tolerate demands for political democracy.
