BEIJING — State Councilor Zhao Kezhi stressed a further crackdown on drug-related crimes, improvements to the system to regulate and control drugs, and implementation of the duties of drug control on May 29.

During a video conference, Zhao, also director of the China National Narcotic Control Commission, required the continuance of campaigns to stop the crime of producing and selling drugs, as well as help drug addicts and control items related to drug production.

He also called for building several systems to fight against drugs, including anti-drug promotion and a global cooperation system for drug control.
