meat products. Ahead of the 2012 Summer Olympics in London, China's Sports Ministry put a ban on local meat products for the athletes, due to the risk of accidental doping from clenbuterol-contaminated meat. The ban came after the World Anti-Doping Agency (WADA) had issued a warning about tainted meat in China and Mexico. Following these events, Yu Juemin, the coach of China's volleyball team spoke out, saying his team's performance was suffering as a result of their imposed vegetarian diet.
