The Proliferation Security Initiative (PSI) was launched by the US President Bush in May 2003. Its main purpose is to prevent the trafficking of Weapons of Mass Destruction (WMD) and related sensitive goods through measures like information sharing, law enforcement cooperation and interdiction.

China is firmly opposed to proliferation of WMD and their means of delivery and stands for the attainment of the non-proliferation goal through political and diplomatic means. China understands the concern of PSI participants over the proliferation of WMD and their means of delivery and shares the non-proliferation goal of the PSI. China supports the cooperation among the PSI participants within the framework of international law. However, the international community including China remains concerned about the possibility that the interdiction activities taken by PSI participants might go beyond the international law.

China, pursuant to its non-proliferation policy, national laws and international commitments, has conducted fruitful cooperation with other countries in the field of non-proliferation recent years. China is ready to continue and further strengthen such constructive exchange and cooperation.
