Notable erstwhile opponents Larry Holmes and George Foreman and other celebrities including former NBA star Shaquille O'Neal were present on Thursday to honour the three-time world heavyweight champion, Xinhua reported.
Ali's fight with Frazier was a 14-round battle known as the "Thrilla in Manila". Ali earned his second victory over Frazier when the former champion didn't come out for the final round, and that fight is considered one of the greatest events in boxing and sports.
Ali, 73, is battling Parkinson's disease. He did not speak during the ceremony.
