In a bid to provide dope-free Asian Games, the China Anti-Doping Agency has conducted nearly 2,000 tests.
A total of 1,950 tests, including 120 blood tests, have been conducted since August, Xinhua reported.
Every single member of the 1,000-strong Chinese delegation for the Games has been tested.
"We hope that China will keep a clean record. We have been working hard to send a clean team to the Asian Games and ensure there is no positive case in our delegation," said Jiang Zhixue, anti-doping chief in China's State General Administration of Sport.
Jiang said the large number of doping tests served as a deterrent measure while anti-doping education is preventive in the fight against drug cheats as the Chinese delegation again adopted the anti-doping education admission system like they did in the National Games last year.
All the athletes were requested to read anti-doping materials and had to sign a letter of commitment, pledging to abide by the anti-doping rules.
"We refined the system that was initiated in last year's National Games," said Jiang. "No athlete is allowed into the team before they finish the required anti-doping education, no matter how great their sport achievements are."
Jiang said the education system will be carried on and extend to provincial and amateur athletes.
"Doping tests are a deterrent measure while education can be preventive. Besides, it is not possible for a country to test all the athletes, both professional and amateur. That's where the education comes in," said Jiang.
