Three Chinese women's weightlifting gold medallists at the 2008 Beijing Olympics were disqualified for doping following a reanalysis of their drug tests, the International Olympic Committee said. It leaves China facing a ban from international competition for a year, a sanction brought in by the sport's governing body the IWF last year to crack down on doping that is rife in weightlifting.Cao Lei, the 75kg champion, Chen Xiexia, the 48kg gold medallist, and Liu Chunhong, who won the 69kg category, were stripped of their 2008 titles. The Chinese trio, all aged between 31 and 34, tested positive for the banned GHRP-2, a human growth hormone.In all, eight athletes were disqualified yesterday from the 2008 and 2012 Olympics in London as part of the ongoing series of retests from 2008 and 2012. Also disqualified were Belarus shot-putter Nadzeya Ostapchuk, who was bronze medallist in Beijing but tested positive for the steroid turinabol.
