Swimming-China's Sun served 3-month banned for doping test

Nov 24 (Reuters) - China's world and Olympic swimming champion Sun Yang served a three-month ban for a failed doping test earlier this year, the Chinese Anti-Doping Agency said on Monday. The agency said Sun tested positive for trimetazidin, a stimulant that was added to the World Anti-Doping Agency's (WADA banned list this year. Sun tested positive in May during the national swimming championships, it added. (Writing by Julian Linden; Editing by Peter Rutherford)
