The event, which is also an Olympic qualifier, will draw athletes from 89 countries and territories, who will be challenging for a place at the London Games.

Phan Thi Ha Thanh and Pham Phuoc Hung will lead the team next month as they attempt to qualify for the Olympic Games.

They will be accompanied by Nguyen Ha Thanh and Hoang Cuong in the men's events and Nguyen Thi Thanh Huyen in the women's disciplines.

Hung, 23, will play a key role for Vietnam at the event, where he hopes to excel on the parallel bars.

At the 2009 World Artistic Gymnastics Championships in Portugal, the Hanoian athlete finished fourth in the men's individual parallel bars, which was the best ever result by a Vietnamese gymnast at a top International Gymnastics Federation event since the country made its debut at the Moscow Olympics in 1980.

Another hope for Vietnam is talented female gymnast Phan Thi Ha Thanh, who pocketed a silver medal in the women's individual vault event in Portugal two years ago.

Lan said that athletes from the top eight teams would be eligible for the London Games, while each team ranking from 9th to 16th in the Tokyo qualifiers would be able to send two athletes.
