Chinese trio retest positive from 2008

The Chinese Weightlifting Association said on Wednesday it was shocked by news that three Chinese lifters were among 15 who have failed retesting of their samples from the 2008 Beijing Olympics.

The association said in a statement it will cooperate with the International Weightlifting Federation in the investigation and reiterated its stance of zero tolerance for doping.

"If, after investigation, activities are found to have violated the rules, the association will not tolerate this, and severe punishment will be meted out," the association said.
