President Obama expressed his commitment to resolving the dispute over Mexican truck access to US highways at the North American Leaders summit meeting on August 9 – 10, 2009. Obama indicated that he will also address safety concerns about the trucks raised by the US Congress. In an effort to find a resolution to the long-standing dispute that will be acceptable to both the Mexican government and members of Congress, US Department of Transportation Secretary Ray LaHood has been developing a set of principles that would address the concerns of Congress, and sharing those principles with the Mexican government to determine if it would consider such principles acceptable.

Effective March 19, 2009, the Mexican Ministry of Economy (SE) issued retaliatory import tariffs ranging from 10 to 45 percent on 89 US agricultural and industrial products in response to the United States’ failure to comply with its commitments under the North American Free Trade Agreement (“NAFTA”) on cross-border trucking services.
