The World Anti-Doping Agency (WADA) has strongly refuted claims of mishandling a 2021 doping case involving more than 20 elite Chinese swimmers who tested positive for a banned performance-enhancing drug. The dispute arose after US Anti-Doping Agency (USADA) chief Travis Tygart accused WADA and Chinese officials of neglecting the rules around drugs in sport.
A local media report revealed that 23 Chinese swimmers, including nearly half of the country's swimming team at the Tokyo Olympics, had tested positive for trimetazidine (TMZ), a banned substance. Despite the positive tests, the athletes were allowed to continue competing, with some even winning medals.
