GOLD COAST, Australia (AP) — Chinese swimmer Sun Yang has been banned from training in Australia and his Gold Coast-based coach Denis Cotterell plans to cut ties with the Olympic and world champion following a positive doping test.

Swimming Australia high performance chief Michael Scott met with Cotterell last week and advised him that Sun was no longer welcome to train at the facility where Cotterell is based.

China's anti-doping agency revealed on Nov. 24 that Sun, who holds the 1,500-meter freestyle world record, served a three-month doping ban earlier this year after testing positive for the banned stimulant trimetazidine on May 17.

Scott said new guidelines had been instituted for any foreign swimmers training in Australia, requiring them to register with the Australian Anti-Doping Agency.

"I met Denis last Tuesday," Scott told the Brisbane Courier Mail. "As a result of that meeting and our policy, Denis has advised the Chinese swimming federation that Sun Yang will not be allowed to train at Miami (Swimming Club) any more or any of our podium centers. Integrity is foremost going forward. It was a very straight-forward call, which Denis supported and has been acted upon already."

A Swimming Australia spokeswoman confirmed Scott's comments to the newspaper.
