The Republic of China (ROC) participated in its first Summer Olympics in 1932 under the name of "China". After the Chinese Civil War, the ROC retreated to the island of Taiwan in 1949, and only Taiwan-based athletes have competed on its behalf since then. In 1971, the ROC was expelled from the United Nations, but was permitted to compete under its official name, flag, and anthem in the 1972 Winter, 1972 Summer, and 1976 Winter Olympics. It was denied official representation in the 1976 Summer Olympics and boycotted it as a result. The 1979 Nagoya Resolution allowed the ROC to compete under the deliberately-ambiguous name "Chinese Taipei"; it protested against this decision and boycotted the 1980 Summer Olympics as well, but has competed under this name since the 1984 Winter Olympics.
