China's swim team embroiled in doping scandal

China's Olympic swim team faces a doping controversy as nearly half of its Tokyo 2021 athletes, including star Zhang Yufei, tested positive for a banned substance. The World Anti-Doping Agency accepted China's claim of contamination. Recent cases involving two swimmers testing positive for an anabolic steroid have intensified scrutiny. Chinese athletes have undergone significantly more tests than their competitors, raising concerns about fairness and performance impact.
