Wang Zongyuan and Long Daoyi won the men's synchronised 3-metre springboard event at the Paris Olympics on Friday to claim the nation's fourth gold in diving.

Both second-time Olympians, the pair finished on 446.10 points.

Wang, 22, previously won gold in the same event in Tokyo three years ago with Xie Siyi, who is only competing in the individual event as defending champion in this year's Games.

The duo trailed after the fourth of six dives, but they rallied on the final two dives to take China's fourth straight gold medal and stay on track for an unprecedented sweep of all eight diving events.

Long and Wang held off the Mexican team of Juan Celaya and Osmar Olvera with 444.03.

Jack Laugher and Anthony Harding of Britain took bronze with a score of 438.15. (Agencies)
