Dozens have died in suspected drug attacks in Mexico in recent days, including a soccer team hostess who was tortured and beheaded in the northern border city of Tijuana and at least 12 killed in a clash between suspected cartel members and police in central Mexico.
Some 1,200 federal police officers were due to be deployed in security operations for the two-day summit starting on Sunday, as well as around 1,000 Mexican presidential guards and other Mexican troops, officials said, declining to be named.
Thousands of extra troops were deployed to the neighboring western state of Michoacan last month in response to a wave of attacks on police by the powerful La Familia drug gang.
With the death toll from suspected drug attacks approaching 10,000 since the start of 2008, Calderon is under pressure to demonstrate success amid growing criticism of alleged abuses committed by some of the tens of thousands of troops deployed in his nationwide crackdown on organized crime.
In Guadalajara, local advocacy groups planned demonstrations Sunday to raise awareness of issues including human rights and the environment.
In a peaceful demonstration Saturday, Greenpeace activists climbed one of the city's main fountains to push for concrete commitments on alternative energy use in the three giant nations ahead of a key climate change summit in December.
Some activists who were detained during a police crackdown on demonstrations during an international summit in Guadalajara five years ago remain in prison without trial, according to Mexican NGOs.
