The USSR did not vote in the resolution to launch a military expedition to relieve the South Koreans because they had chosen to boycott the UN earlier in the year as a result of their anger in the Security Council's refusal to hand over the Republic of China's (Taiwan) permanent seat over to the People's Republic of China.

Consequently, the UN Security Council Resolutions of 82/84/85 which precipitated the American-led UN force in Korea were not vetoed by the USSR.
