Vietnamese Nguyen Thi Anh Vien was not successful at the Barcelona World Swimming Championships but did manage to set up two new Southeast Asian Games records.

Vien on August 4 competed in the women's 400m medley event with a time of 4min 4.60sec, finishing 21st. She failed to earn a berth in the final round but her result is a new national record. It is also a new Southeast Asian (SEA) Games record beating the old one 4:50.88 set by swimmer Natthanan Junkrajang of Thailand in 2011.

Earlier, Vien set a record in the women's 200m backstroke event with a time of 2:12.75. The old SEA Games record of 2:14.95 was her own, made in June during the ASEAN age-group swimming championships in Brunei.-VNA
