NPR's Carrie Kahn reports from Mexico City, Obama says he wants to talk the economy,
but security matters will also be topping his agenda.
The streets surrounding Mexico City's historic center have been closed for hours in anticipation of President Obama's arrival.
Enthusiastic supporters and a few protestors made a path to police barriers in front of national palace, where Obama is meeting with Mexican President Enrique Pena Nieto.
Obama said he came to discuss trade and the economy.
Mexico is the United States third largest trading partner.
Economic trade across the two countries' borders now tops $1 billion a day.
But a recent decision by Mexican officials to curb U.S. anti-drug agents access in the country will likely dominate discussions.

Just today, after the arrest of three friends of the Boston Marathon bombing suspect,
law enforcement is continuing to follow leads.
NPR's Dina Temple-Raston reports officials are looking for clues on his laptop .
For more than a week now, law enforcement officials have been trying to get an idea of what bombing suspect Dzhokhar Tsarnaev did in the weeks leading up to the Marathon attacks.
His laptop computer is expected to give them those clues.
The three men arrested on charges that they helped Tsarnaev after the bombing had grabbed two things from his dorm room,
a backpack full of empty fireworks canisters and the young man's laptop computer.
Forensics experts are combing through the computer's hard drive now, looking for things Tsarnaev searched for and possibly deleted.
It could take days or even weeks however to find the clues that might be buried there.
