The United Nations General Assembly resolution 498 was approved on February 1, 1951, in response to the intervention of Chinese Communist troops in Korean War.
[1] The General Assembly vote followed unsuccessful attempts by the U.S. delegation to the United Nations to have the Security Council take action against the Chinese Communists.
Exercising his nation's veto power, the Soviet representative on the Security Council consistently blocked the U.S. effort.
Turning to the General Assembly, the U.S. delegation called for the United Nations to condemn communist China as an aggressor in Korea.
While economic and political sanctions could have been brought against Red China, the United Nations decided to take no further action.
