In the 10th minute, midfielder Nguyen Thi Tuyet Dung scored the opener for Vietnam, and allowed the team to get on the front foot, but Pham Hoang Quynh, captain Huynh Nhu and Nguyen Thi Lieu were all unable to beat Myanmar goalie Zar Zar Myint.
After the break, Vietnamese coach Mai Duc Chung made some changes and rookie Nguyen Thi Van doubled the score for Vietnam in the 68th minute.
Just a few minutes later, taking full advantage of a defensive error, striker Pham Hai Yen added a third, and despite their efforts, Myanmar were unable to get on the scoresheet.
The Vietnamese footballers are due to return home on July 14 to prepare for the Asian Games to be held in Indonesia in August.
