MANILA, May 7 -- The United States and the Philippines participated in a virtual Proliferation Security Initiative (PSI) workshop last week to demonstrate their shared commitment to preventing the spread of weapons of mass destruction (WMD). Through briefings and discussions of regional proliferation issues, as well as maritime scenario discussions, the United States and the Philippines explored ways to best confront proliferation threats and leverage laws and regulations to stop proliferation. The Defense Threat Reduction Agency (DTRA), a U.S. Defense Department agency that works to counter and deter weapons of mass destruction and improvised threat networks, organized the workshop, which involved participants from across the governments of both countries. U.S. participants from the Departments of Defense, State, and Homeland Security joined Philippine rep resentatives from the National Security Council, the Departments of National Defense and Foreign Affairs, the Anti-Terrorism Center, the National Coast Watch Center, and the Strategic Trade Management Office.
