UN adopts Resolution 83.

Following the invasion of South Korea on 25 June, the United Nations Security Council adopted Resolution 83 and authorized member states to provide military assistance to South Korea.

The vote in favour was because the USSR, which could have vetoed the resolution, had made an error in boycotting the proceedings in protesting at the Chinese Nationalists on Taiwan island, and not the Chinese Communists in control of mainland China, assuming China’s seat on the Security Counci.

The UN decision cleared the way for the United States to take the lead in commanding the United Nations Command (UNC) led by General Douglas MacArthur that would provide the military assistance to South Korea and expell the North Koreans from South Korea.

Nations contributing combat and or support units to the UNC were:

Australia
Belgium
Canada
Colombia
Denmark
Ethiopia
France
Greece
India
Italy
Luxembourg
Netherlands
New Zealand
Norway
Philippines
South Africa
South Korea
Sweden
Thailand
Turkey
United Kingdom
United States of America
