China's synchronised swimmers have made history in the pool in the early hours of Thursday, as they put on a dominant performance on the final day of competition to secure their first-ever gold medal at the Olympics.

The national team were already runaway leaders after the first two routines which took place in the past two days.

But the silver medallists in Tokyo had everything to lose coming into the last performance, the acrobatic routine.

Going last out of 10 teams, the octet of Chang Hao, Feng Yu, Wang Qianyi, Wang Ciyue, Wang Liuyi, Xiang Binxuan, Xiao Yanning and Zhang Yayi once again finished first on 283.6934 points.

That pushed their accumulative score to 996.1389 points, near 82 ahead of the United States and 95 in front of Spain.

That broke a two-decade stronghold by Russia, as the six-time defending champions were banned from the Olympics over the conflict with Ukraine.
