Sino-US Doping War Escalates Ahead of Paris Olympics The Chinese anti-doping agency (Chinada) has claimed that there are "reasons to believe that there is a problem of systemic doping in the athletics environment in the United States," in a statement on Thursday. This statement, part of the war of words between the two global sports powerhouses, comes on the day of the 200m final at the Paris Olympics, where American sprinter Erriyon Knighton, a double world medallist, will compete. Knighton, who tested positive for an anabolic steroid on March 26, 2024, was cleared by the US Anti-Doping Agency (USADA) due to a dietary contamination, just before the US Olympic trials. #sinousdopingwar,#parisolympics2024,#chinada,#usada,#antidoping,#athletesdoping,#sportsdiplomacy
