WASHINGTON, Jan. 13 (Xinhua) -- U.S. President George W. Bush met with his Mexican counterpart Felipe Calderon here on Tuesday, pledging continued bilateral cooperation on border security and narco trafficking.

    "The less drugs we use, the less pressure there'll be in Mexico. We have got responsibilities to help prevent guns from going from the United States into Mexico," Bush told reporters after his final White House meeting with Calderon.

    Calderon, who has been striving for curb drug-related killings in homeland, also vowed to continue "fighting criminals and to overcoming them once and for all."

    The United States is in good relations with neighboring Mexico. In his meeting with Calderon on Monday, U.S. President-elect Barack Obama also promised to beef up relations with Mexico City.

    New U.S. presidents traditionally meet with their Mexican counterparts either before they are inaugurated or shortly afterward. Obama will be inaugurated on January 20.
