OBAMA ARRIVES IN MEXICO FOR START OF SUMMIT

GUADALAJARA, Mexico -- President Barack Obama began a summit meeting
here Sunday night with his Mexican and Canadian counterparts that
touched on a broad range of issues including climate change, the
economic crisis, the swine flu pandemic and the battle against illegal
drugs.

The annual meeting was started four years ago as a way for the
neighboring countries to build on ties established by the North
American Free Trade Agreement. As much as they bring the countries
together, the meetings have also served to highlight deep differences,
particularly on trade and immigration.

Expectations were low that those differences would be resolved in the
whirlwind of meetings on Sunday and Monday.

"I think the summit is going to be a step in the continuing dialogue
from which agreements will undoubtedly come," Gen. James L. Jones, Mr.
Obama's national security adviser, said before the meetings began. "I
think we'll see more of these dialogues. And as I said, from that, I
think good things will come."

Immigration was raised again, but this time tensions were expected to
be focused on Mexicans entering Canada, not the United States.

Too many Mexicans, the Canadian government complained, are
fraudulently claiming political asylum in Canada, overwhelming the
system. So Canada announced last month that it would begin requiring
Mexican citizens to secure visas before entering the country, a
decision that elicited outrage in Mexico.

The Mexicans struck back with an announcement that Canadian diplomats
and government officials would now require visas to enter Mexico.

Although some angry Mexican lawmakers urged President Felipe Calderon
to go further and require visas for all Canadian visitors, Mr.
Calderon held off, not wanting to damage Mexico's tourism industry,
which relies heavily on North American visitors.

Mexico also raised a trade dispute that began when the United States
Congress canceled a program, in violation of Nafta, that allowed
Mexican trucks to operate in the United States.

Mexico responded by imposing billions of dollars in tariffs on
American products. The Obama administration said it was seeking to
resolve the dispute, but did not have a deal ready in time for the
meeting.

Another irritant is the "Buy American" clause in the Obama
administration's economic stimulus plan, which both Canada and Mexico
oppose. An aide to Prime Minister Stephen Harper of Canada told
reporters last week that he "wouldn't be surprised" if the Canadian
leader raised the issue of protectionism with Mr. Obama.

Even on the issue of combating Mexico's drug violence there is
political discord. The American aid package for Mexico says that 15
percent of the funds can be disbursed only if the State Department
decides that the Mexican government meets certain human rights
conditions. Reports that Mexico's army has engaged in torture and
other abuses while carrying out the drug war have prompted some in
Congress to oppose releasing those funds.

Mr. Calderon's government has characterized any abuses as isolated.
And in a meeting with reporters before Mr. Obama's trip to Mexico this
week, his aides defended the army's record and argued for the aid to
be released.

The Obama administration has indicated that it favors giving the
aid.

"I think the Calderon government has, in fact, performed very
courageously in the face of these cartels, and I think we have to do
everything we can to be a helpful neighbor and partner," said General
Jones, the national security adviser.

Another topic on the agenda is the political crisis in Honduras, where
the provisional government and the president it sent into exile in a
cou p in June, Manuel Zelaya, have been unable to come to terms.

The country's interim leader, Roberto Micheletti, said Sunday that he
would not allow a delegation of the Organization of American States
and regional delegates to enter Honduras for crisis talks this week if
the O.A.S. secretary general, Jose Miguel Insulza, was among them. Mr.
Micheletti accused Mr. Insulza of lacking "impartiality and
professionalism."

A senior White House official said that he believed there was still
time to work out an arrangement for the delegation's visit, scheduled
for Tuesday, and news agencies later reported that Mr. Micheletti's
government said that a meeting could be held if Mr. Insulza was only
an observer. It was not clear when the meeting might take place.

The delegation had planned to visit Honduras to build support for a
proposed settlement forged in negotiations mediated by President Oscar
Arias of Costa Rica. The plan calls for Mr. Zelaya to return as
president, although with significantly limited powers.
