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]
