Why did the Communists invade China?

The Communist Party of China, led by Mao Zedong, did not invade China; rather, it emerged from a civil conflict against the Nationalist government (Kuomintang) after years of war and social unrest. The Communists sought to establish a socialist state by addressing issues such as poverty, inequality, and foreign domination. They gained significant popular support during the Chinese Civil War, culminating in their victory in 1949, which led to the establishment of the People's Republic of China.
