TOLUCA, Mexico President Barack Obama met Wednesday with his Mexican and Canadian counterparts but little tangible came out of the Three Amigos summit, a further sign that the world's largest trading bloc is on autopilot, hobbled by spats between members.
Indeed, Obama spent his first moments of an abbreviated eight-hour stay focused on a public statement about turmoil in distant Ukraine a country with which U.S. annual trade doesn't equal even two days' worth of business with Mexico.
In one sign of consensus, Obama, Canadian Prime Minister Stephen Harper and Mexican President Enrique Pena Nieto agreed to harmonize a "trusted traveler" program, synchronizing a handful of different programs to speed border crossings around the hemisphere.
But the overall atmosphere in Mexico's fifth largest city was cool, a sign of the strains that separate the leaders and have slowed momentum to modernize the North American Free Trade Agreement, or NAFTA, which celebrates its 20th anniversary this year.
A bilateral spat between Mexico and Canada, and anger in Ottawa over U.S. indecision on whether to build the Keystone XL pipeline from western Canada to the U.S. Gulf Coast did not appear to get resolved at the summit. Obama and Harper said the two discussed Keystone, which would carry oil made from tar sands, but Obama insisted that his administration must await further determinations about the potential impact of the pipeline on climate change.
"We only have one planet," Obama said.
NAFTA, the world's largest trade bloc, comprises 470 million people from Canada's Yukon to the Yucatan Peninsula in Mexico. The bloc represents nearly 30 percent of global economic output.
But leaders face pressures from special interests in each country, and Obama, speaking in the late afternoon next to Harper and Pena Nieto, said the leaders need help from voters to "deepen what are already incredible ties between our three nations."
"We have every incentive to make this work," Obama said. But he cautioned that, "you just can't leave it to politicians alone."
Issues surrounding NAFTA dwarf the economic impact of other global issues facing any of the three nations, yet more dramatic world events tend to overshadow efforts to strengthen the North American alliance.
Over 8 million U.S. jobs depend on trade with Canada, and another 6 million on trade with Mexico. Trade between the three nations tops $1 trillion a year.
Experts say the NAFTA alliance has drifted with a lack of strategic vision.
"Twenty years later, it's hard for us to talk to each other and reach agreement," said Laura Macdonald, a political scientist who specializes in the region at Carleton University in Ottawa.
Rather than re-debate NAFTA, Obama pressed Pena Nieto and Harper to speak with one voice as they negotiate the Trans-Pacific Partnership, a proposed trade accord that includes 12 countries around the Pacific Rim. Obama dismissed a suggestion that he can't get the accord through his own party in Congress.
"We'll get this passed if it's a good agreement," Obama said.
Minutes before he disembarked from Air Force One, Obama signed a new executive order to reduce bureaucratic barriers and speed up imports and exports, a move intended to help businesses strengthen supply chains across borders. The move signaled that Obama would not cede to opposition, much of it within his own Democratic Party, to his trade agenda.
Yet multiple tensions surrounded the summit, and McDonald said it unfolded "at the worst moment in the trilateral relationship" since the Sept. 11, 2001, terror attacks in the United States triggered concerns over border security.
The bright spot is an energy revolution that is altering the global energy map and shifting its epicenter to North America, revitalizing manufacturing.
"We are in a fundamentally different place than we were even five years ago," said Eric Farnsworth, vice president of the Council of the Americas, a Washington, D.C.-based business group that promotes free trade, democracy and open markets in the hemisphere.
