Beijing - Chinese swimmer Chen Xinyi has failed a
doping test at the Rio Olympics, the official Xinhua news agency reported
Friday, citing the Chinese Swimming Association (CSA).
She tested positive for
hydrochlorothiazide, a diuretic, on Sunday, it said. On that day the 18-year-old
took part in the women's 100m butterfly final, finishing fourth.
Chen has applied to the International
Olympic Committee for her B sample to be tested and for a hearing, it added.
Diuretics increase urination rates and can

performance-enhancing substances that are screened for in doping tests.
Chen first made the headlines when she won

China has already been embroiled in doping
controversy in Rio after Australia's Mack Horton called Sun Yang, China's most
successful swimmer, a "drugs cheat" - inciting a social media

French swimmer Camille Lacourt also waded

radio station: "Sun Yang, he pisses purple."
In March, the CSA revealed that six Chinese
swimmers had tested positive for drugs in the preceding months, including three
for hydrochlorothiazide. Two of the six athletes were disciplined with only
Swimmers from other countries have also
been caught up in disputes in Rio.
After American Lilly King beat tainted
Russian rival Yulia Efimova in the 100m breaststroke final, she said: "I
think it just proved that you can compete clean and still come out on top."
US superstar Michael Phelps has demanded
life bans for swimmers with a drug record.
An explosive report by the World
Anti-Doping Agency (WADA) alleged a state-run doping conspiracy across Russian
sport, with world athletics chief Sebastian Coe this week blasting Moscow's
"cataclysmic failure" to protect athletes.
All but one of Russia's track and field
athletes were banned from Rio, but the International Olympic Committee decided
to allow other Russians to compete in Rio, despite calls for the team to be
