The Proliferation Security Initiative PSI was formed to increase international cooperation in interdicting shipments of weapons of mass destruction WMD, their delivery systems, and related materials. The Initiative was announced by President Bush on May 31, 2003. PSI does not create a new legal framework but aims to use existing national authorities and international law to achieve its goals. Initially, 11 nations signed on to the Statement of Interdiction Principles that guides PSI cooperation. As of August 2009, 95 countries have committed formally to the PSI principles, although the extent of participation may vary by country. PSI has no secretariat, but an Operational Experts Group OEG, made up of 20 PSI participants, coordinates activities.
