The meeting took place Sunday during a U.S./Canada/Mexico summit in Guadalajara, Mexico. Obama presented Calderon with a road map to "a definitive solution in the short term" to the trucking dispute, said Arturo Sarukhan, Mexico's ambassador to the United States.

Obama reportedly made clear his commitment to work with Congress to address safety concerns about allow Mexican trucks free range to operate on U.S. highways. Presently Mexican trucks may travel only 25 miles in from the border, and then must transfer their goods to an American truck for further transportation. The North American Free Trade Agreement requires open trucking, but Congress in March abolished a pilot project to permit Mexican trucks farther into the country over safety concerns. That sparked retaliatory tariffs by Mexico on $2.4 billion worth of U.S. exports, infuriating many American businesses that rely on selling goods to Mexican customers.

U.S. Commerce Secretary Gary Locke said Monday at a meeting of the Americas Society and the Council of the Americas that the U.S./Mexican trucking dispute is a major concern to the Obama administration. Locke noted U.S. Transportation Secretary Ray LaHood is working with members of Congress to find a solution that will be approved by lawmakers.
