A 35-strong team includes world beach cup champions and 31st Southeast Asian (SEA) Games winners Phùng Thị Huệ, Đào Hồng Sơn and Hoàng Thị Nhật Quế.
The event in the Thai capital Bangkok will take place at Rangsit University' campus, in Pathum Thani.
Organisers announced that more than 500 athletes from 30 countries and territories have registered for the tournament, a record number of participants.
Việt Nam is aiming to win three gold medals.
"For week, we have increased the volume of exercises for athletes to improve their fitness and technique," said coach Bùi Đình Tiến who also organised internal matches between his fighters to help them familiar with competition environment and pressure.
"We also watched video clips as references in which we learned from high-ranking athletes, analysed their techniques and found suitable solutions to fight back."
Meanwhile Trần Văn Thạch of the Việt Nam Sports Administration said the plans for training and competing were drawn up earlier as there were many tournaments for the team in 2023.
"We hope to bring home at least three golds at this tournament which is a key event ahead of the 32nd SEA Games in May in Cambodia and the Asian Games in September in China," said Thạch.
At the 2022 championship in Bahrain, Việt Nam finished fifth with five golds, three silvers and eight bronze medals.
All golds went to world champion Huệ in the women's 45kg newaza, fighting and contact. Huệ was awarded best athlete on the second competition day.
Her teammate Dương Thị Thanh Minh secured her two titles in the women's 52kg newaza and contact.
Defending champions Huệ and Minh are favourites to make top podiums again.
Young athlete Quế is another golden hope as after her world beach cup title in the women's 57kg class last June.
"I am working hard to sharpen my technique. With strong support from coaches I am confident heading to the coming tournaments and grab high result," Quế said.
The Vietnamese team will leave for Bangkok on February 20. It is the last international event for the team prior to the Phnom Penh SEA Games.
At the last Games in Hà Nội, Việt Nam came second with two golds, one silver and two bronze medals. /.
