President Bush on Monday said, "We celebrate the enduring and close partnership between our countries. Mexico and the United States are working together to build a future of prosperity and opportunity for people on both sides of the border. And at this ceremony, we also celebrate the comeback of a great American city. You know, I chose New Orleans for our meetings with Mexico and Canada because I wanted to send a clear signal to the people of my country that New Orleans is open for business, and it's a good place to visit, and that after the devastation of Katrina, it's become a hopeful city."
