Serious test of the IOC's mettle to go up against a power like China and take strong action.23 members of the Chinese swim team appararantly doping. Not surprised really. This is no difference to the Russia style systematic doping in the past 10 years, not only swimming but other sports as well.. Seriously need to call for a ban on the whole team. Puts into doubt recent swims by Pan Zhanle, Zhang Yufei and Qin Haiyang in the past few years. Maybe they are getting practice for the Enhanced Games in a few years time.
