China's women's and men's 4x100m relay squads secure final berth at Tokyo Olympics

Men's 100m finalist Su Bingtian led the men's 4x100m squad with Xie Zhenye, Tang Xingqiang and Wu Zhiqiang. They won the heat at 37.92 seconds, second best among the eight finalists, only behind Jamaica.

"We aimed to break the national record in the final," said Asian record holder Su.

The United States' men's team failed to qualify to the final as they ranked a disappointing sixth in the heat.
