Mexican officials, including economy secretary Ildefonso Guajardo, who leads the Nafta talks, have insisted that the negotiations be limited to the content of the agreement itself, and not include immigration.
But the issues are still linked Mr. Trump, who tweeted last month: "Mexico, whose immigration laws are very strict, must prevent people from crossing Mexico and the United States, we can make this a condition for the new NAFTA Agreement ".
Officials from both countries met on Thursday for the first of two days of scheduled talks on a series of immigration-related issues.
Sarah Huckabee Sanders, the White House press secretary, declined Thursday to comment on the ongoing negotiations, but said that, in terms of immigration, "The president wants to see Mexico intensify and do more."
Until last Friday, Mexican officials thought they had reached a compromise with their US counterparts over a key part of the Naphtha as an agreement was reached on standards that would increase the participation of the content of a car in the region to to have the right to zero tariffs and the rules that govern the minimum wages of those who work in automobiles, according to a Mexican government official with knowledge of the subject. conversations
Mexicans have been eager to finalize an agreement before their presidential election, which is scheduled for July 1. The Americans, believing that Mexicans would bend in the rules of the car to reach an agreement quickly, insisted on a harder position and Mexicans responded by rejecting the proposal, saying they would prefer not to have a deal than a bad deal, according to officials informed about the conversations.
Michael C. Camuñez, a former official of the US Department of Commerce, said: Lighthizer pressed last week for the three countries to reach a separate agreement on the auto industry. In return, Mexico had expected flexibility in some points of dispute, he said.
