"To increase the attraction of VBA, one additional spot for foreign players in each club has been allowed. Domestic players will also get to learn from these foreigners by playing alongside them. This is necessary for Vietnamese basketball because in SEA Games, strong teams like the Philippines have many foreign players with strong physical skills," said Tran Chu Sa, CEO of VBA.
"We have decided to limit the total height of the two foreign players in a team at under four meters to make it easier for local players to compete," Sa said.
