Record-breaking Liu rekindles Tokyo belief

China scooped four more golds on Sunday to bring its total haul to nine at the two-day Beijing meet.

Three-time Olympic champion Sun Yang dominated the men's 400m freestyle, taking the lead after two laps to win in 3:44.98 ahead of compatriot Ji Xinjie (3:47.04) and Danas Rapsys of Lithuania (3:49.62).

"Three titles in five days, I am pretty happy with my performance as I've managed to stay smooth and steady in every race," said Sun, who also claimed golds in the 200 free in Beijing and the 400 free in Shenzhen.

"It is the only international event we can have before the Olympic Games, it is like a rehearsal for us," added the Chinese captain.

Yu Jingyao collected gold for China in the women's 100 breaststroke in 1:07.18, while Yang Junxuan broke the Chinese national record by winning the women's 200 free in 1:54.98.
