The New York Times recently reported an undisclosed case involving 23 top Chinese swimmers testing positive for a banned substance just before the Tokyo Olympics. Despite being cleared by China’s antidoping authorities and the World Anti-Doping Agency, this has sparked concerns in the antidoping community. The investigation identified five events in which these swimmers won medals, raising questions about the legitimacy of their victories. However, both Chinese and WADA officials defended their handling of the case, stating that the swimmers unknowingly ingested the banned substance. Despite criticism, there are no indications of race results or medal allocations being affected.
