Crisis for China as swimmer Chen Xinyi fails drugs test at Rio Olympics
China says it will cooperate during the investigation and repeats it resolutely opposes use of banned substances

China plunged into a doping crisis at the Rio Olympics today with swimmer Chen Xinyi failing a drugs test.
The Chinese Swimming Association confirmed that 18-year-old Chen tested positive for diuretic hydrochlorothiazide on August 7, the day she finished fourth in the 100m butterfly final.
Chen has applied to the International Olympic Committee (IOC) for testing of her B sample and a hearing to look into the matter, said the Chinese Swimming Association.
“The CSA has taken this matter seriously and demanded full cooperation from Chen in the investigation,” the CSA said.
“The CSA resolutely opposes use of banned substances. We will cooperate with the Court of Arbitration of Sport during its investigation and will respect the final ruling by the CAS.”
