Japan entered into conflict against the Chinese in 1937. The Japanese invasion and occupation of parts of China resulted in numerous atrocities against civilians, such as the Nanjing Massacre and the Three Alls Policy. The Japanese also fought skirmishes with Soviet–Mongolian forces in Manchukuo in 1938 and 1939. Japan sought to avoid war with the Soviet Union by signing a non-aggression pact with it in 1941.
