[1] This was the third International Crown, a biennial match play event contested between teams of four players representing eight countries.

Due to the anticipated arrival of Typhoon Kong-rey, the tournament schedule was adjusted; the second round tee times were moved earlier on Friday and the third round, originally scheduled for Saturday, was started on Friday afternoon.

These five remaining teams were re-seeded based on points earned in pool play.

The total points earned in pool and singles play determined the team champion.
