With Công, he won the Vietnamese league championship in 1998, and in early 1999 they went on to win the Super Cup after defeating the Vietnam Police football club in Hồ Chí Minh City.
During his first championship in charge, he took the team to the top spot, but by the end of the season Bình Dương had dropped back to the bronze medal position.
The team's biggest defeat, losing 5–0 to Đà Nẵng at the Chi Lăng stadium, led to Vương's resignation after only a year with the club.
