Regulation of precursors is a concern of the international community and to China. In 2009, the relevant agencies considered the existing laws and ways to strengthen them. Within the industries there have been regulations circulated to enhance internal regulation within the industries.
Chemicals of particular concern have been identified and China has worked to monitor flows of these substances in partnership with the INCB. China has cracked down hard on smuggling and illicit sale of precursors. China and EU have signed a joint cooperative agreement on precursors to prevent the flow of these chemicals into illicit markets. Hopes source and transit countries will share information with China so gaps can be closed quickly.
