The president-elect of Mexico, Enrique Pena Nieto, said he wants to expand his country's drug-war partnership with the United States but that he would not support the presence of armed American agents in Mexico.

Mr Pena Nieto said he would consider hosting US military instructors on Mexican soil, but in a training capacity only, to help his soldiers and marines benefit from US counter-insurgency tactics learnt in Iraq and Afghanistan.

He also approves of the continuation of flights by US surveillance drones over Mexico to gather intelligence on drug trafficking, but future missions would be run by Mexico with US assistance and technology.

''Without a doubt, I am committed to having an intense, close relationship of effective collaboration measured by results,'' Mr Pena Nieto said.
