President-elect Barack Obama takes a brief break today from his focus on the domestic economy for a meeting with Mexico's president.
Obama is showing support for Felipe Calderon's efforts to battle drug cartels. Drug-related killings in Mexico doubled last year and violence has spilled over the border.
Just last month, the Justice Department called Mexican cartels the biggest organized crime threat to the United States.
Trade is one area where the two men don't see eye-to-eye.
Obama has suggested he'd like to renegotiate the North American Free Trade agreement to give U.S. workers more protection. But at a meeting of Pacific Rim leaders last November, Calderon said doing that would create "not more markets and more trade, but fewer markets and less trade."
