This article briefly outlines the history of the conflict between Communist China and the Soviet Union. Before 1949, tensions grew as matters of territory, national pride, and specific approaches to Communist theory in the two nations clashed. In 1950, when the Communist party seized control of the government of China, the two nations signed a friendship treaty. However, tensions slowly began to build until 1960, when the Chinese began talking about the inevitability of war.
