This will be the first appearance of Vietnam in the Toulon Tournament.[3] The Republic of Ireland was originally scheduled to the tournament, but later pulled out due to budget restriction.[4] Australia has also declared interests in participating in the competition.
The twelve teams will be drawn into three groups of four. In the group stage, each group will be played on a round-robin basis. The teams will be ranked according to points (3 points for a win, 1 point for a draw, and 0 points for a loss). If tie on points, the following criteria will be used to determine the ranking: 1. Goal difference; 2. Goals scored; 3. Fair play points. The group winners and the best runners-up will qualify for the semi-finals.
