Seventeen-year-old female Vien, who has returned home from the United States, is set to shine in her favourite events, 200 metre backstroke and 400 metre medley, while Phuoc will hopefully win gold in the men's 200-metre freestyle event.

At last year's 27th SEA Games in Myanmar, Vien won three gold medals and Phuoc won one gold.

Vien has become the first Vietnamese swimmer winning a berth to play in the 400-metre medley event at the World Swimming Championships in Russia in 2015.

She showed off her amazing talent by winning four gold and two silver medals at the recent 2014 Florida Swimming Spring Senior Championship in Orlando, Florida. She then continued to stun the US swimming scene by bagging four more gold and two additional silver medals from her six registered events at the 2014 NASA Junior National Championship.

Phuoc also topped the 2014 National Short Course Swimming Championships by winning 15 gold medals.

The 38th edition event will see Singapore play host to nine other participating SEA countries for the various swimming events in three age categories: 16–18; 14–15; and 13 and under.

A total of 263 athletes will be competing in the tournament, with 73 gold medals up for grabs.
