The Asian Football Confederation (AFC) has fined the Vietnam Football Federation (VFF) $13,750 for fans lighting flares during the game with Indonesia, and $25,750 fine for flares as well as a bottle of water being thrown onto the field during the match between Vietnam and Thailand in AFC U23 Championship qualifiers in March.

This is the fourth time that VFF has been fined for failing to stop Vietnamese fans from firing flares during a continental level matches.

If such incidents are repeated, AFC will hand out harsher punishments, including being forced to forfeit a game.

Last year, some fans lit flares in the stands of the Pakansari stadium in Indonesia during the semifinal match of the Asian Games 2018 between Olympic Vietnam and Olympic South Korea last August. For that, VFF was fined $12,500.

VFF also had to pay $15,000 for flares lit during a 2018 game in the Asian Cup 2019 qualifying tournament.
