FIFA fined the Hong Kong Football Federation on Wednesday after some fans booed and whistled the Chinese national anthem at a World Cup qualifier against Iran on September 10.
"The March of the Volunteers" was whistled by fans before the game in which Team China's Hong Kong lost 2-0 to Team Iran.
As a Chinese Special Administrative Region (SAR), the national anthem is played for Team China's Hong Kong before their games.
The Disciplinary Commission of the world football's governing body handed the federation a fine worth 15,000 Swiss francs (13,700 euros) because of "disturbance during national anthems; use of objects to transmit a message that is not appropriate for a sports event."
Team China's Hong Kong is third in Group C of the Asia zone after playing Iraq on Wednesday. Their next home game is against Team Bahrain on November 14.
