MEXICO CITY — Ending a three-day trip to Colombia and Mexico, John McCain praised Mexican drug-fighting efforts Thursday and hailed a U.S. aid package for security forces here as a key step in bilateral relations.
McCain, the presumptive Republican nominee for president, said the so-called Merida Initiative approved by Congress last week was an "important sign of progress and cooperation to fight the drug cartels and the flow of drugs into the United States."
The aid measure will provide $400 million to Mexico in police training and equipment next year.
The Arizona senator spoke after touring the high-tech command center of a gleaming new federal police facility. He was joined by his wife, Cindy, and close political allies Sen. Joe Lieberman (I-Conn.) and Lindsey Graham (R-S.C.).
McCain met earlier with Mexican President Felipe Calderon and said the two discussed immigration and trade. McCain has sought to highlight differences with his Democratic opponent, Barack Obama, over the trade issue.
McCain is a strong backer of the North American Free Trade Agreement, which covers the United States, Mexico and Canada, and he supports a free-trade pact with Colombia.
Obama, an Illinois senator, opposes the Colombia agreement without labor and human rights improvements in that nation, and favors renegotiating NAFTA to get better labor and environmental safeguards.
McCain spent 24 hours in Mexico after a two-day visit to Colombia, where he praised that nation's drug-interdiction efforts.
On his Mexico stop, McCain reiterated his support for allowing more immigrant workers to enter the United States on a temporary basis. But he said broad immigration reform should come only after the U.S. government has tightened the border adequately, including by building fences.
Migration is a big issue in Mexico, the main source of undocumented immigrant labor in the United States. Mexican migrants in the United States sent home about $24 billion in remittances last year.
"We must have comprehensive immigration reform, but the American people want our borders secured first," McCain said.
McCain's visit to Mexico, seen by some commentators here largely as a play for Latino votes in the United States, came as the Calderon government has pursued a crackdown on drug trafficking.
That effort, and scattered turf wars among traffickers on the U.S. border and elsewhere, has fed a spiraling death count that unofficial tallies put at more than 1,750 this year.
