When China unveiled its roster of 31 swimmers set to represent the country at the upcoming Paris Summer Games, 11 of the competitors remain embroiled in a doping scandal from the previous Olympics that continues to send shockwaves across the sporting world and beyond. According to an April New York Times report, 23 Chinese swimmers had, months before the Tokyo Olympics in 2021, tested positive for trimetazidine (TMZ), a prescription heart drug that can enhance performance and has been banned by the World Anti-Doping Agency (WADA) since 2014.
