BEIJING nike air force 1 bianche e blu , Dec. 19 (Xinhua) -- China's double Olympic champion Sun Yang has been under fire since the news broke that he had served a doping ban earlier this year.
It was the most shocking news of Chinese swimming in 2014 and has caught world-wide attention.
The star swimmer has been barred from training in Australia and his Australian coach Denis Cotterell isn't allowed to coach Sun as a result of the new policy to be implemented by Swimming Australia.
The Chinese Swimming Association (CSA) announced last month that it had banned Sun for three months from May 16 to Aug. 17 as he had tested positive for the banned stimulant trimetazidine during the national championships in May.
The CSA believed in Sun's innocence and said Sun had offered enough evidence to prove he had no intention to take the drug to improve his performance.
Sun's national 1,500m freestyle title was stripped.
