Chinese swimmers going to Paris are undergoing increased drug testing - at least eight times this year - before the Games, World Aquatics said.
The final roster named 11 athletes who tested positive for a banned heart medication in 2021, six months before the Tokyo Olympics. They avoided being suspended and proceeded to win three gold medals.
A Chinese state-backed investigation in June 2021 blamed mass contamination by food in a hotel kitchen though without evidence. The case was not publicly revealed until it was reported three months ago
Chinese athletes competing in Paris "will be tested ... no less than eight times during this same period," the governing body said. Those samples would ideally not be collected by the Chinese anti-doping agency and not be tested by laboratories in China.
World Aquatics is set to publish those test results before the Olympics opening ceremony next Friday. "What is extremely clear is that the trust of the aquatics community is vital to the continued success of World Aquatics as an international federation," the governing body said.
Meanwhile, a panel recommended World Aquatics routinely publish details of who is provisionally suspended for potential breaches of anti-doping rules. It also wants details published of how often athletes were tested, and by who.
