Authorities step up anti-doping campaign

One month before the Pyeongchang Winter Olympics in South Korea, China is stepping up its anti-doping campaign.

Taking a zero-tolerance stance on the issue, Chinese sports authorities are tightening up their doping controls on competition-bound teams in addition to their routine tests.

The number of tests conducted by the China Anti-Doping Agency (CHINADA) now annually exceeds 10,000.
