Several members of the Chinese national swimming team remain embroiled in a doping scandal.
The swimmers in question have been under fire since testing positive for the banned heart medication trimetazidine in 2021.
The World Anti-Doping Agency (WADA) ultimately cleared the athletes for competition at the Tokyo Olympics.
Last month, the Chinese Swimming Association selected some of those athletes for its 2024 Olympic team. The swimmers are preparing to travel to compete in Paris later this month.
