BEIJING (AP) — China's decision to ban a top swimmer for life for a failed drug test proves the country is serious about sending a clean team to the Olympics, a top anti-doping official said Monday.

Swimmer Ouyang Kunpeng and his coach, Feng Shangbao, were permanently barred from the sport last week after he tested positive for anabolic steroids. The decision was an embarrassment for the host country just six weeks before the Beijing Olympics.

Zhao Jian, deputy director general of the China Anti-Doping Agency, told The Associated Press the case illustrates that China is "resolutely determined" in making sure its athletes are clean.

"It shows China has a very systematic and strict anti-doping program, which includes ... all of the best athletes. The system is running effectively," he said.
