Japan–Korea disputes

Kim founded North Korea, and his descendants have still not signed a peace treaty with Japan. The Provisional Government of the Republic of Korea, led by (later) South Korea's first president Syngman Rhee, moved from Shanghai to Chongqing. Lee lobbied in the United States and was recognized by the South Korean administrator by Douglas MacArthur.
