what is south korea relationship with the united states
South Korea–United States relations South Korea–United States relations (Hangul: 한미 관계; Hanja: 韓美 關係; RR: Hanmi gwangye; MR: Hanmi kwan'gye) have been extensive since 1950, when the United States helped establish the modern state of South Korea, also known as the Republic of Korea, and fought on its UN-sponsored side in the Korean War (1950–1953). During the subsequent four decades, South Korea experienced tremendous economic, political and military growth, and significantly reduced U.S. dependency. From Roh Tae-woo's administration to Roh Moo-hyun's administration, South Korea sought to establish an American partnership, which has made the Seoul–Washington relationship subject to some strains, especially with the Anti-US/Korean sentiments. However, relations between the United States and South Korea have greatly strengthened under the conservative, pro-U.S. Lee Myung-bak administration. At the 2009 G20 London summit, U.S. President Barack Obama called South Korea "one of America's closest allies and greatest friends."[1] In addition, South Korea has been designated as a Major non-NATO ally.[2]
Korean War The Korean War (in South Korean Hangul: 한국전쟁; Hanja: 韓國戰爭; RR: Hanguk Jeonjaeng, "Korean War"; in North Korean Chosŏn'gŭl: 조국해방전쟁; Hancha: 祖國解放戰爭; MR: Choguk haebang chǒnjaeng, "Fatherland: Liberation War"; 25 June 1950 – 27 July 1953)[38][39][b] was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea[41][42] following a series of clashes along the border.[43][44] The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
