\In addition to unprecedented cooperation between the two countries in fighting drugs and organized crime, foreign direct investment between Mexico and the U.S. has grown exponentially in the last 20 years.

Mexico is the United States' second-largest export market, and one in 24 Americans depend on trade with Mexico for their jobs, according to a 2011 report by the Washington-based Mexico Institute.

"Both governments have invested time, resources and credibility in building a security partnership that didn't exist five to six years ago. They don't want to see that undermined by the malfeasance or stupidity of individuals," said Andrew Selee, Mexico Institute director. "It's a conscious attempt to compartmentalize and deal with specific incidents on merits rather than dynamiting the overall relationship."
