The international swimming governing body has confirmed that its executive director has been ordered to testify in a US criminal investigation related to a case involving 23 Chinese swimmers who failed doping tests in 2021. These swimmers, despite testing positive for the banned substance trimetazidine, were allowed to continue competing and even won medals at the Tokyo Olympics.
According to reports, the Chinese swimmers tested positive for trimetazidine several months before the 2021 Tokyo Olympics. The World Anti-Doping Agency (WADA) has banned trimetazidine since 2014 due to its performance-enhancing properties. However, China's anti-doping agency claimed that the swimmers were not at fault as they were inadvertently exposed to the substance.
