Originally having participated in Olympics as the delegation of the Republic of China (ROC) from 1924 Summer Olympics to 1976 Winter Olympics, China competed at the Olympic Games under the name of the People's Republic of China (PRC) for the first time at the 1952 Summer Olympics held in Helsinki, Finland, although they only arrived in time during the last days to participate in one event. That year, the International Olympic Committee (IOC) allowed both the PRC and ROC to compete with the name "China", although the latter withdrew in protest. Due to the dispute over the political status of the "two Chinas", the PRC started a period of isolationism, withdrawing from several international sporting bodies and the UN system until the mid-1970s, when the country participated for the first time in the Asian Games in 1974 and the World University Games in 1977. Returning to the IOC officially only in 1979, which gave it the right to send an official delegation, starting from the 1980 Winter Olympics in Lake Placid, United States. Their first appearance at the Summer Olympic Games after 1952 was the 1984 Summer Olympics in Los Angeles, United States. The People's Republic of China staged boycotts of the Games of the XVI Olympiad in Melbourne, Australia, Games of the XVII Olympiad in Rome, Italy, Games of the XVIII Olympiad in Tokyo, Japan, Games of the XIX Olympiad in Mexico City, Mexico, Games of the XX Olympiad in Munich, Germany, and Games of the XXI Olympiad in Montreal, Canada. China also boycotted the Games of the XXII Olympiad in Moscow, Soviet Union due to the American-led boycott and the ongoing Sino-Soviet split, together with the other countries.
