Chinese swimmers in Paris Olympics

At the Paris Olympics, China clinched gold in the men's 4x100m medley relay with a time of 3:27.46, narrowly beating the USA, which finished in 3:28.01, ending a streak of 10 consecutive Olympic golds for the Americans in this event. The USA set a new world record in the women's 4x100m medley relay with 3:49.63, surpassing their own previous record. Despite the success, China's swimming team faced scrutiny due to a doping controversy, as two members of the gold medal-winning relay team, Qin Haiyang and Sun Jiajun, were among 23 athletes who tested positive for the banned substance trimetazidine prior to the Tokyo Olympics. China's internal investigation suggested food contamination was the cause, a claim accepted by the World Anti-Doping Agency. The team's overall performance in Paris improved from their Tokyo haul, achieving 12 medals despite the backdrop of the doping allegations. American swimmer Katie Ledecky emphasized the need for reform to ensure fair competition, highlighting the ongoing concerns over doping regulations in international sports.
