Details of the center were announced at the opening of special Beijing exhibition, which showcases the International Olympic Committee's 40-year anti-doping history and urges the Chinese public to become more aware of the dangers of drugs.

"Anti-doping should not be the only task for sports people, but for all the common people," said Yang Shu'an, executive vice-president of BOCOG.

"To popularize the anti-doping knowledge to the public is the responsibility of officials. We hope more young people could realize the danger of the drugs and refuse to take illegal drugs actively."

Yang said the Chinese Olympic Anti-doping Commission (COAC) was getting tough on its own athletes.

"In the recent year, China has increased the testing numbers among its athletes and ordered heavier punishment on the positive cases," said Yang.

"The number of the positive cases in China is much smaller than the average level of the world."

COAC is also on track to finish its doping control center for the 2008 Games.

It is believed to be the largest and most advanced doping control center in the world and will test record numbers at the 2008 Beijing Olympic Games.

More than 4,500 cases will be tested in Beijing, 25 percent more than at the 2004 Athens Games (3500 tests) and exactly 50 per cent more than Sydney (3,000 tests).

"During the Games time, the staff in the laboratory is expected to over 100," said Du Lijun, vice director of National Research Institute of Sports Medicine.
