The Security and Prosperity Partnership of North America (SPP) was a region-level dialogue with the stated purpose of providing greater cooperation on security and economic issues.[1] The Partnership was founded in Waco, Texas, on March 23, 2005, by Prime Minister of Canada Paul Martin, President of Mexico Vicente Fox, and U.S. President George W. Bush.[1] It was the second of such regional-level agreements involving the United States following the 1997 Partnership for Prosperity and Security in the Caribbean (PPS).
Since August 2009 it is no longer an active initiative of any of the original dialogue partners. It has been largely superseded by the annual North American Leaders’ Summit, an event that was established as part of SPP.
