Thailand generated more scoring opportunities but failed to deliver their attempts home in front of more than 25,000 fans.
However the Milovan Rajevac’s side proved more effective in the shoot-out. Goalkeeper Kawin Thamasatchanan denied the first two kicks from Gabon to give the home team in the driver’s seat at the start of the duel and the momentum remained with the home team ever since.
Thailand will go for the fourth consecutive title as they take on the Slovak Republic, the 2-1 winner over UAE on Sunday.
