The events before and during World War II had a big impact on China. Beginning in 1931, the Japanese invaded China. In 1931, the Japanese invaded Manchuria, in northern China, to capture the resources of the region. Then, in 1937, Japan continued its invasion of China. The Chinese were forced to move their capital from Beijing to Chongqing because of the Japanese invasion. Throughout World War II, Japan controlled Chinese territory. Japan also controlled the major Chinese ports. During the Japanese occupation, the Japanese committed brutal acts toward the Chinese. There were massacres and atrocities which took place. Many Chinese died in these actions. Also during this time, women were abused by the Japanese. The United States tried to help China in World War II with the Lend-Lease Act. However, this wasn't as successful as the Lend Lease Policy was with Great Britain. China was greatly impacted by the events before and during World War II.
World War II provided an opportunity for the growth and subsequent takeover of the Nationalist government by the Communist party. Although the Nationalists were better equipped with more men and territory, they were actively engaged in the fight with Japan.
The failure to adequately address the internal threat led to territorial losses for the Nationalists, and in some areas the Communists took over without a fight. The situation led to the end of the Nationalist government and the establishment of the People’s Republic of China.
The war also saw a shift in alliances for China. The United States, which was allied to the Nationalist government led by Chiang, was not a favorite of the ruling Communist party. The Soviets, on the other hand, signed treaties and made concessions with the People’s Republic. Thus, the war resulted in complex Sino-American relations.
