Sun served a three-month suspension after testing positive for banned stimulant trimetazidine in 2014, and his appearance at Rio 2016 has caused controversy, with Australian Mack Horton particularly critical.
Sun was beaten to gold in the 400m freestyle by Horton but topped the podium in the 200m final (Lacourt finished fifth).
