| The Sunday Times reported an alleged dispute 
				between doping testers and the swimmer last year which the 
				newspaper said had resulted in damage to a sample.
 China's swimming association (CSA) said an investigation by 
				world swimming body FINA had found the swimmer committed no 
				anti-doping rule violation.
 
 The CSA said Sun had rejected an out-of-competition doping test 
				at his home in China on Sept. 4 last year over what the athlete 
				said was a lack of proof of identification by the testers.
 
 "After FINA called up an investigation of the issue, CSA ordered 
				Sun Yang to fully cooperate with FINA and truly report every 
				detail of the affair," the CSA said in a statement to state-run 
				news agency Xinhua.
 
 "According to the final decision of the FINA Doping Panel, FINA 
				confirms the athlete did not commit an anti-doping rule 
				violation."
 
 FINA could not be immediately reached for comment, while the 
				World Anti-Doping Agency said it was looking into the matter.
 
 "I can confirm that WADA is aware of this case and that we are 
				following up accordingly," Maggie Durand, WADA's manager of 
				media relations and communications said.
 
 Sun, a triple Olympic gold medalist and world record holder, was 
				banned in 2014 for three months after testing positive for the 
				banned stimulant trimetazidine during the Chinese national 
				championships.
 
 His lawyer Zhang Qihuai has threatened legal action, saying the 
				newspaper reported with "a malign intention" which "severely 
				damaged Sun Yang's reputation and violated his privacy."
 
 "We reserve the right to file a lawsuit against the relevant 
				international media which reported the incident," Zhang said in 
				a statement to Xinhua.
