An October 3 letter from the Business Roundtable, the Canadian Council of Chief Executives, and the Consejo Mexicano de Hombres de Negocios urged President Obama, Canadian Prime Minister Stephen Harper, and Mexican President Enrique Pena Nieto to address border systems, regulatory cooperation, and energy security and sustainability. The letter noted that barriers to doing business exist between the three countries despite the North American Free Trade Agreement. The groups recommended improving energy project permitting processes and promoting North American renewable energy resources.
