The Thai women's team won the AFF Women's Championship in an action-packed dramatic finale that ended with a 6-5 shoot-out following a 1-1 draw after 120 minutes on Thursday night.
It is the Kingdom's third triumph in the Southeast Asian championship.
Vietnam, thanks to their persistence, had come from behind to level the score just five minutes from time to force the game into extra time.
Thailand had taken an early lead through Rattikan Thongsombut in the 12th minute.
In the shoot-out, the score was tied at 3-3 after five penalty takers each.
In the sudden death, both sides were level until the fourth kick where Tran Thi Phuong Thao slammed her shot down the middle and it was saved by Thailand goalkeeper Waraporn Boonsing.
For Vietnam, it was a tough loss especially after their dramatic semi-final comeback the previous day when they equalised in extra time, forced the game into penalties, and went on to surprise hosts Myanmar.
In the final, Thailand surprised their rivals by snatching an early lead through Rattikan who deflected in a shot from Duangnapa Sritala.
The Vietnamese players picked up the pace and began looking for breaches in their opponents' defence.
But the Thais stood strong with their goalkeeper Waraporn turning away all attempts that went her way.
With Vietnam calling the shots, Thailand were limited to counter-attacks which never really threatened their rivals.
The script was very similar after the break with Vietnam taking the fight to their opponents.
The Vietnamese strikers were harsh in their search for goal. It was their fighting spirit and determination which eventually led to the equaliser.
Both sides could not score in extra time and the match went to penalties.
The match was the two teams' second meeting in this tournament. In the group stage, Vietnam surprised Thailand 2-0 to finish as group winners.
