Nguyen Thi Thanh Truc took her gold in the women's over-70kg Jujitsu Gi category. The Asian and Asian youth champion faced no difficulties beating four rivals from the Philippines and the hosts in a round-robin format event to top the podium.
The other gold went to Tran Hong An in the women's U18 U57kg class.
Vietnamese fighters also took bronze medals in the women's U57kg by Nguyen Thi Minh Vuong and women's U18 U48kg by Tran Thi Hoang Van.
The Thai tournament was held from June 20-23 featuring hundreds of competitors from more than 30 countries and regions. High-ranking athletes would collect points to earn their spots at the World Jujitsu Championships and World Youth Jujitsu Championships later this year.
After the Thailand Grand Prix, Vietnamese martial artists will take part in the Southeast Asian Jujitsu Championship on July 4-8 in Bali, Indonesia.
