Andrew Selee, president of the Migration Policy Institute in Washington, saw a change from past Mexican leaders who were "obsessed" about being on good terms with the United States.
Lopez Obrador said that he has already met with businessmen after his crushing victory in Sunday's election and that he planned a Tuesday night meeting on inviting worldwide figures - including Pope Francis, rights activists and the United Nations - to help come up with a plan to solve Mexico's problem of soaring violent crime.
"We are not going to fight".
"This new national project will seek to establish an authentic democracy and we do not intend to establish a dictatorship", Lopez Obrador said.
The peso was down 1.5% to 20.1568 versus the USA dollar at 9:30 a.m. ET after preliminary results from Mexico's electoral commission showed Lopez Obrador sweeping up more than half the vote.
Conservative Ricardo Anaya of a right-left coalition and the PRI's Jose Antonio Meade acknowledged defeat shortly after polls closed nationwide.
Sunday's win by longtime political outsider Andres Manuel Lopez Obrador, who takes office on December 1, was expected by markets, though his margin of victory was wider than projected and it appears his coalition will have a majority in Congress. "The tone was respectful, and our teams will be holding talks".
"I see that the results [of the voting] are favorable for Lopez Obrador".
"We will only be able to create better conditions for development for everyone if we get personally involved in the improvement of our municipalities, states and the entire Mexican Republic", they said. He added the private sector would defend recent initiatives, such as an energy reform bill that opened the sector to private investors under President Enrique Pena Nieto, "that have benefited competitiveness". While his allies are forecast to likely dominate both houses of congress, he may not enjoy the two-thirds majority needed for outright reversal. The party also scooped a range of important governorships in Mexico City, Morelos, Chiapas and Tabasco.
The victory was a vindication for Lopez Obrador, who was written off by many critics after narrowly failing to capture the presidency at his first bid in 2006.
He also plans to tour the country without secret service protection, and to dissolve the guard corps that has protected presidents since 1926.
Since Sunday, Lopez Obrador's every move has been broadcast live, with journalists and supporters forming a slow-moving convoy around the 64-year-old, who has pledged to shed various trappings of power including the presidential residence and plane, while earning half of Pena Nieto's salary.
Amid widespread frustrations with the status quo, all of the candidates have tried to paint themselves as the agent of real change. But he's been frustratingly vague on how he'll go about it.
"I think he's going to try and help us with the border". But it does represent a major shift - representing the largest margin of victory by any candidate in Mexican history.
Mexican presidents serve six years and can not be re-elected.
"It's really a question of when the talks resume", Ross said.
Lopez Obrador vows to improve Mexicans' lives by ending corruption and years of drug violence, while also reducing the wealth gap.
"In the case of Mexico, obviously we share a border with them (and) this president has made very clear about building that wall and having Mexico pay for it", the aide, Kellyanne Conway, said on Fox News.
