Who did the superpower support in the Chinese civil war?

During the Chinese Civil War, the United States primarily supported the Nationalist Party (Kuomintang or KMT) led by Chiang Kai-shek, providing military and financial aid in an effort to prevent the spread of communism. Conversely, the Soviet Union supported the Chinese Communist Party (CCP) led by Mao Zedong, offering military assistance and strategic guidance. This international involvement reflected the broader ideological conflict of the Cold War, with both superpowers aiming to expand their influence in Asia. Ultimately, the CCP emerged victorious in 1949, establishing the People's Republic of China.
