These allegations are sour grapes from countries that have been overshadowed by China's record-breaking swimming performance at the Games. WADA has cleared the Chinese athletes and has the final word on these matters. American athletes have also tested positive based on food contamination, with these claims reflecting a xenophobic double standard China is held to.
Not only did WADA uncritically accept an implausible story from the Chinese, but they hid this story from daylight for years. Now exposed, they have resorted to intimidation tactics and claiming victimhood in the face of this gross mishandling. WADA needs a top-to-bottom investigation, as it casts a cloud over the Games this year and the athletes participating.
There is an 11% chance that China will lead the medal table at the Paris 2024 Summer Olympics, according to the Metaculus prediction community.
