Sawt Falasteen - Dos Santos at the double, Jackson and Russell shine in Xiamen

Brazilian Dos Santos, who beat Warholm in the 300m hurdles at last week's series opener in Shanghai/Keqiao, timed 46.72 seconds for victory over 400m hurdles at Xiamen's Egret stadium.

Warholm came in second, at 0.10sec, after tying up badly over the final two hurdles.

"It felt good. I always try to get the speed up at 300. I cannot go too fast at the beginning of the race so I am excited with the time," said Dos Santos.

Jamaica's Jackson stole the show in the women's 200m, underlining her status as one to watch this season.

The two-time world champion clocked an electric 21.87sec, a meet record, and was the sole sprinter to go sub-22sec.

American Sha'Carri Richardson came in fourth in 22.38sec.

Richardson's partner Christian Coleman could only finish seventh in the men's 100m.

Victory in that race was claimed by Kenya's Ferdinand Omanyala in 9.94sec.

Botswana's Letsile Tebogo, the Olympic 200m champion, was eighth in the blue riband event in 10.10sec, but there was at least one of his teammates who won on a hot and humid night of high-quality action.

Busang Collen Kebinatshipi, an Olympic silver medallist in the 4x400m relay who won world 400m gold in Tokyo last year, stormed to a dominant victory in the one-lap race.

The 22-year-old clocked a meet record of 43.92sec for his first ever Diamond League win.

American Russell clocked an outstanding 12.14sec for victory in the 100m hurdles, an Americas and Diamond League record.

The Olympic champion's time was just two-hundredths of a second off the world record.

Arguably the standout performance of the meet in the field was by home favourite Yan Ziyi, who smashed her own under-20 world record by winning the women's javelin with a massive 71.74 metres.

The 18-year-old bettered her previous mark by almost nine metres for a distance that was an Asian and Diamond League record, as she edged ever closer to the world record of 72.28m set by Czech Barbora Spotakova in 2008.

There was another meet record in the women's 3,000m steeplechase, won by Uganda's 2021 Olympic champion Peruth Chemutai in a world lead of 8:51.06.

Chemutai, who kicked off her season with victory in Shanghai/Keqiao, benefitted from a mistake on the final hurdle by current Olympic champion and world number two Winfred Yavi.

American Jamal Britt also made it two from two by winning the 110m hurdles in 13.07sec.

He finished ahead of Japan's Rachid Muratake, with slow-starting world champion Cordell Tinch only fifth in 13.28.

World record holder Ryan Crouser made his long-awaited Diamond League return -- after missing most of last season through injury -- and finished third.

Jamaica's Rajindra Campbell won with a national record of 22.34m, the American managing 21.41.

There were also meet records in the men's 5,000m, won by Ethiopian Addisu Yihune in 12:57.32, and long jump, which went the way of Greece's two-time Olympic champion Miltiadis Tentoglou (8.46m).

Australia's Abbey Caldwell claimed victory in a high-quality women's 1,500m, outsprinting Ethiopia's Birke Haylom in a winning 3:57.26.
