Asia's fastest man, Su Bingtian, has backed Chinese sprinters to keep improving after a summer when the 32-year-old became the first athlete from the country to reach the final of the 100 meters at the Olympic Games.

Su led the United team — essentially China's national squad — to gold in the 4x100 meters relay at the National Games on Friday, following his performance in the Tokyo Games, where he broke the Asian record in the semifinals of 100 meters.

The Guangdong native, who finished sixth in the 100 meters in Tokyo, also won gold in the individual event this week at the National Games in Xi'an. He expressed confidence China is producing sprinters capable of following in his footsteps.
