China's top sports governing body approved new anti-doping regulations following a swimmer's doping incident.

The General Administration of Sport of China unveiled on Wednesday an undated version of anti-doping regulations, to take effect on Jan 1, in accordance with the World Anti-Doping Code. Along with the new regulations, the sports administration also released new guidelines explaining the changes and specifying penalties.

One of the highlights is requiring authorities to investigate and punish officials, coaches and anti-doping executives who obstruct tests, interfere with evidence collection and delay processing, instead of punishing athletes alone.
