Nguyen Thi Anh Vien set a new record at the second Southeast Asia Swimming Championships in Singapore on June 20.

The 17-year-old won the gold in the women's 200m butterfly event with a timing of 2:12.46. It was 4.79sec faster than the old record made in 2012 by Arieswati Lorenza Monaliza of Indonesia.

Sarisa Suwannachet of Thailand and Tan Jing-E of the hosts came second and third, respectively.

Vien later pocketed her second gold of the day in the 100m backstroke event when she finished with a time of 1:02.72.

Indonesian Yessy Yosaputra and Thai Natthanan Junkrajang trailed her for silver and bronze, respectively.

Vien has collected six golds and four records after four days.

Other Vietnamese were not as successful as their teammate on the day.

Hoang Quy Phuoc bagged the silver in the men's 100m butterfly event while Tran Duy Khoi took the bronze in the men's 400m individual medley category.

On June 19, Vien won three gold medals on the third day of competitions.

Vien defeated two Singapore rivals Nur Marina and Lim Meagan to finish first, with a time of 1:00.69 in the women's 100m butterfly round, which is not Vien's strong point.

In the 50m backstroke discipline, she finished with a time of 29.51sec, beating her old record of 29.89sec made at the same event in Singapore two years ago.

The Can Tho city-born swimmer also came first in the 400m medley with a time of 4:49.03, breaking her old record of 4:50.27.

Her teammate Phuoc snatched a silver medal in the 400m freestyle with a time of 3:57.09, just behind gold medallist Danny Yeo Kai Quan of Singapore who finished with a time of 3:57.06.

In day two, he came in first in the men's 200m freestyle, while Vien topped the women's 400m freestyle.

Singapore temporarily take the lead with nine golds, nine silvers and eight bronzes. Thailand are in second with seven golds, eight silvers and seven bronzes, while Vietnam are third with seven gold, four silvers and two bronze medals.

This biennial event, which brings the region's aquatic community together in spirited competition during a non-SEA Games year, will last until June 24.-VNA
