During the 1992 Barcelona and 1996 Atlanta Opening Ceremonies, Costas's remarks on China's teams' possible drug use caused an uproar among the American Chinese and international communities. Thousands of dollars were raised to purchase ads in "The Washington Post" and Sunday "The New York Times", featuring an image of the head of a statue of Apollo and reading: "Costas Poisoned Olympic Spirit, Public Protests NBC". However, Costas' comments were made subsequent to the suspension of Chinese coach Zhou Ming after seven of his swimmers were caught using steroids in 1994. Further evidence of Chinese athletes' drug use came in 1997 when Australian authorities confiscated 13 vials of Somatropin, a human growth hormone, from the bag of Chinese swimmer Yuan Yuan upon her arrival for the 1997 World Swimming Championships. At the World Championships, four Chinese swimmers tested positive for the banned substance Triamterene, a diuretic used to dilute urine samples to mask the presence of anabolic steroids. Including these failed drug tests, 27 Chinese swimmers were caught using performance-enhancing drugs from 1990 through 1997; more than the rest of the world combined.
