SwimSwam reports that Xu’s 22.03-second relay opening leg in Beijing lowered Pieter Coetze’s mark, set earlier in October, by 0.06 seconds.

China’s Xu Jiayu swam the opening 50m backstroke leg of the mixed medley relay final in 22.03 seconds at the Chinese Short Course Championships in Beijing on October 24, 2026, according to SwimSwam. The outlet reported the time as a world record, 0.06 seconds faster than the mark South Africa’s Pieter Coetze set earlier in October.
Short-course swimming uses a 25-metre pool. Xu’s time came in the first leg of a relay rather than an individual 50m final. The mark’s official ratification status is unclear.
Coetze recorded his 22.09 at the World Cup stop in Tashkent. Xu’s previous personal best and Asian record dated to the 2018 World Cup, according to SwimSwam.

| Pieter Coetze | 22.09 seconds | Previous world record, earlier in October 2026 |

The 22.03 swim cut 0.67 seconds from Xu’s previous best. SwimSwam also reported it as a Chinese national record and an Asian record.
Xu’s Zhejiang Shouxian Valley team went on to win the mixed medley relay in 1:37.51, SwimSwam reported. The championships began on October 23 and are scheduled to continue through October 28.

SwimSwam reports a 48.77-second victory in Beijing, lowering Xu’s eight-year-old mark by 0.11 seconds at a meet where swimmers are competing for world championship places.
