The World Anti-Doping Agency and Chinese officials have signed an agreement to crack down on the manufacture and supply of performance-enhancing drugs in China.
WADA announced the "memorandum of understanding" on Tuesday with the General Administration of Sport of China.
WADA says the agreement "signifies a significant breakthrough" in clamping down on illegal production of doping products in China "which are then exported to the outside world and all too often reach the hands of athletes."
The agency says the deal follows a recent US Drug Enforcement Administration investigation that led to a large amount of doping products being seized, much of it obtained over the Internet from Chinese companies and laboratories.
WADA and Interpol, the international police organisation, will provide information to Chinese law-enforcement organizations for targeting illegal suppliers.
