The boycott of the 1984 Summer Olympics in Los Angeles was after the U.S.-led boycott of the 1980 Summer Olympics in Moscow. The boycott involved 14 Eastern Bloc countries and allies, led by the Soviet Union, which initiated the boycott on May 8, 1984. The boycott affected a large number of Olympic events that were normally dominated by the absent countries. Boycotting countries organized another major event, called the Friendship Games, in July and August 1984.
The USSR announced its intentions to boycott the 1984 Summer Olympics on May 8, 1984, citing security concerns and “chauvinistic sentiments and an anti-Soviet hysteria being whipped up in the United States.” A US official said the country had ignored suggestive comments by the Soviets in the weeks building up to the announcement and that, in spite of all the indications, the United States was “absolutely dumbfounded” when the official announcement arrived.
After the announcement, six more nations joined the boycott, including Bulgaria, East Germany (on May 10), Mongolia and Vietnam (both May 11), and Laos and Czechoslovakia (both May 13). China formally confirmed that it would be present at the games in Los Angeles, while the Laotians and Czechoslovaks announced their decision to boycott the event.
Later, Afghanistan also decided to boycott the event, becoming the eighth country to boycott the 1984 Summer Olympics. Even later, Hungary (May 16) and Poland (May 17) became the ninth and tenth communist countries to join the boycott. Hungary claimed the lives of its athletes would be put in danger if they were to spend time in Los Angeles. On the other hand, Poland said that the United States was engaging in a “campaign aimed at disturbing the Games”.
