On April 2, 2012, President Obama hosted Prime Minister Stephen Harper of Canada and President Felipe Calderon of Mexico for the North American Leaders’ Summit (NALS) in Washington, DC. This meeting built on wide-ranging and ongoing cooperation among the United States, Canada, and Mexico with a particular focus on economic growth and competitiveness, citizen security, energy, and climate change. The leaders also discussed North America’s role in the Americas in anticipation of the Summit of the Americas in Cartagena, Colombia later in April, as well as other global economic, political, and security issues.
