China's teenage skateboarders, Japan's cyclists and a Thai Esports player bagged gold medals on Day IV of the Asian Games on Wednesday.

At the end of the day, China's medal count hit 140, followed by South Korea way behind with 70.

At the skate park, 13-year-old Cui Chenxi became China's youngest Asian Games gold medallist when she won the women's street event.

With an eye-catching performance featuring several 'Ollies' and a huge move off a high rail, Cui took gold ahead of compatriot Zeng Wenhui, 18, with Japanese 16-year-old Miyu Ito taking bronze.

Cui, who hails from China's eastern Shandong province, only took up skateboarding in 2020 when China's Covid restrictions meant she could not practice rollerblading, which she began as a three-year-old.

The street competition involves skaters performing daring tricks on a course that has features that resemble an urban environment including rails and gaps.

'Tough battle'

Earlier, Yu Yuting, 18, just held on for victory over Japan's Ageha Tanigawa, 20, in the women's 400m medley.

"It was really a tough battle out there, and it was very close towards the end," Chinese swimmer Yu said. "I gave it everything I had, and had nothing left in the tank when I touched the wall."

While China's men's football team progressed to the quarter-finals, Thailand won the Asian Games' first gold medal for the online version of the beautiful game.

In an all-Thai final Teedech Songsaisakul beat his compatriot and close friend Phatanasak Varanan 2-0 to take the gold in the online football game EA Sports FC Online, with South Korea's Kwak Junhyouk picking up bronze.

China won the Games' first Esports gold on Tuesday in the 'Arena of Valor' multiplayer battle game.

Kuwait's 60-year-old Abdullah Alrashidi impressed on the shooting range with a world record-equalling performance in the men's skeet to get his country's first gold of the Games.

In the event where the shotgun-wielding athletes attempt to shoot and break clay targets fired into the air at high speeds and varying angles, Alrashidi held off a strong challenge from India's Anant Jeet Singh Naruka to take the win.

"Today I only missed one target from 110 targets," the veteran of seven Olympics said.

"This happens when you play every day, exercise, go swimming, and eat well."
