MOSCOW (AP) _ Sergei P. Pavlov, once head of the state sports committee that organized the 1980 Olympics, has been named ambassador to Burma, the official news agency Tass said Monday.

Pavlov was fired from his job as chief of the sports committee in early 1983, just after the late Yuri V. Andropov took power as Communist Party chief, and was then appointed ambassador to Mongolia.

Tass announced in April that Konstantin Y. Fomichenko, formerly ambassador in Ethiopia, had been named to replace Pavlov as ambassador in Ulan Bator.

Pavlov, 56, headed the sports committee for 15 years and before that was chief of the Komsomol, the Communist Youth League. In Burma, he replaces Vladimir N. Kuznetsov, 68, who Tass said had retired.
