Teenager Ye Shiwen defended her record-breaking performances in the pool in London, saying it was a result of hard work and dedication.
The 16-year-old, after winning the 400 meter individual medley in record time, was questioned by several coaches, with the executive director of world swimming, John Leonard, calling the female swimmer's performance "unbelievable, disturbing and suspicious".
Ye, who completed an Olympic double with gold in the 200 meter individual medley on Tuesday, staunchly defended her swims in the London Olympics in front of a packed press conference.
"They are biased," Ye said. "In other countries people have won multiple medals and people have said nothing.
"Why are they just criticising me? I have absolutely not taken anything."
Ye added she always had a good physique for swimming, and was noticed at a young age by coaches in China. She also said she could envisage more and more young swimmers succeeding in the sport, particularly pointing out the success enjoyed by American 17-year-old Missy Franklin.
"The teacher in my kindergarten noticed I had a good physique so they picked me," she said. "I do well because of our training.
"It is two-and-a-half hours in the morning and the same in the afternoon. I've been doing it for nine years.
"It's very likely that swimmers will keep getting younger. There will be more people even more capable."
Australian Alicia Coutts and American Caitlin Leverenz, who came in second and third respectively, defended the Chinese teenager.
"I like to believe in innocent until proven guilty," Coutts said.
"As far as I'm concerned she's innocent and I think she's an amazing swimmer and it's just amazing to be as close as I was."
"It's easy to point fingers but you can do that at any of the other racers," Leverenz added. "She has proved that girls can go faster than the men. I want to congratulate Shiwen on what she has achieved."
Earlier, British Olympic Association chairman Lord Moynihan called for an end to the controversy, after Ye passed her doping test. "She's been through Wada's programme and she's clean," Moynihan said. That's the end of the story. Ye Shiwen deserves recognition for her talent."
Head of IOC's medical commission, Arne Ljungqvist, said: "Personally I don't have any reason other than to applaud what has happened."
