The current division of the Korean Peninsula is the result of decisions taken at the end of World War II. In 1910, the Empire of Japan annexed Korea and ruled over it until its defeat in World War II. The Korean independence agreement officially occurred on 1 December 1943, when the United States, China, and the United Kingdom signed the Cairo Declaration, which stated: "The aforesaid three powers, mindful of the enslavement of the people of Korea, are determined that in due course Korea shall become free and independent". In 1945, the United Nations developed plans for trusteeship administration of Korea.
