List of ambassadors of the United States to South Korea
At the end of World War II, American forces accepted Imperial Japan's surrender in southern Korea, and Soviet forces accepted the surrender of the Japanese in northern Korea. Talks to agree upon a unity government for Korea failed and in 1948, two separate Korean states were created: the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea). The United States established diplomatic relations with the new South Korean government, but did not recognize North Korea. Other countries, like the Soviet Union, recognized the Pyongyang government in North Korea, but did not initially establish relations with the South Korean government in Seoul.
South Korea–Taiwan relations
The People's Republic of China (PRC) was founded in 1949 following the Chinese Civil War and Republic of Korea maintained relations with the Republic of China (ROC), whose government relocated to Taiwan. The United Nations condemned North Korea's military aggression against Republic of Korea in United Nations Security Council Resolution 82 and United Nations Security Council Resolution 84. The ROC voted in favor of both United Nations resolutions. During the Korean War, the ROC supplied material aid to ROK, while the People's Republic of China gave North Korea combatants to support the People's Volunteer Army.
