" President Barack Obama arrived in Mexico for his first three-way summit with leaders of the United States neighbors to the north and south. The president landed in Guadalajara on Sunday evening, slated to begin a quick two-day visit with his counterparts from Mexico and Canada. The swine-flu outbreak, which started in Mexico and since spread across the world, was at the top of the agenda. Mr. Obama will discuss this and a host of other issues with Mexican President Felipe Calderon and Canadian prime Minister Stephen Harper. Outside of the swine flu, the three men are expected to work on trade, immigration, drug trafficking and security issues, as well as clean energy. President George W. Bush kicked off the trilateral tradition in 2005 with the first summit, called the North American Leaders Summit, held near his Texas ranch."
