The first conference scheduled in September 2020 will bring together governments, businesses, experts and scholars from Asia and other parts of the world to discuss cooperation in economic development and security, said Zeng Weixiong, deputy director of the China National Narcotics Control Commission, who serves as president of the conference.

Wang, also director of the China National Narcotic Control Committee, made the remarks at a national teleconference on drug control.

The country has "zero tolerance" toward illegal drugs and has staunchly supported and implemented the three United Nations drug control conventions, the China National Narcotics Control Commission said.

The National Narcotics Control Commission said that China has signed 50 intergovernmental and interdepartmental cooperation documents on drug control with more than 30 countries and international coalitions, and established annual meeting mechanisms with 13 nations.

Immigration authorities nationwide seized about 8.9 metric tons of narcotics and 712 tons of precursor chemicals last year, the National Immigration Administration released on Tuesday.
