Nine nations compete in the Games to be held in Laos for the first time from December 9 to 18.
The competition is split into two groups, with Thailand in Group A along with five other teams. Apart from Vietnam, the defending champions face Malaysia, East Timor and Cambodia, while hosts Laos, Singapore, Indonesia and Burma make up Group B.
Steve Darby, assistant to national-team football coach Bryan Robson, was unhappy with the draw in the larger group, which means Thailand will play more games in the group stage.
