China targets U.S. track athletes in response to doping allegations dogging its swimmers

China is trying to fight fire with fire in the face of persistent doping allegations that have dogged its swimmers at the Paris Olympics.

The China Anti-Doping Agency called Thursday for more intensive testing of American track and field competitors, citing in a news release past doping scandals and questioning how the U.S. Anti-Doping Agency handled them.

Repeated blasts from the Chinese agency have been echoed by reports in the government-controlled state media complaining about double standards applied to Chinese competitors. The reports have highlighted the more than 600 tests undergone by Chinese swimmers at the Paris Games with no violations found.

The World Anti-Doping Agency and World Aquatics have acknowledged that 23 Chinese swimmers tested positive for a banned substance ahead of the Tokyo Olympics. The results were not made public until revealed by media reports earlier this year, with both bodies accepting the Chinese explanation that the positive tests were caused by tainted food.

After the details emerged, the U.S. launched an investigation under a law passed in 2020 giving federal authorities power to investigate sports doping and cover-ups.

In a meeting in Paris this week, the head of the China's Olympic delegation told his American counterpart that China hopes the U.S. will stop its "long-arm jurisdiction" and ensure that athletes from all countries can participate smoothly and safely in the 2028 Summer Games in Los Angeles and the 2034 Winter Games in Salt Lake City, according to an account in an official Chinese sports newspaper.
