Mexico City’s former mayor won the presidency in a landslide victory earlier this month. He will take over from Pena Nieto on December 1.
The two want to "work as one and present a united front for Mexico, that’s how we work on our relationship with the United States," Foreign Minister Luis Videgaray said at a press briefing.
Secretary of State Mike Pompeo and Homeland Security Secretary Kirstjen Nielsen led a high-level delegation to Mexico City on Friday to discuss bilateral issues such as border security, trade and migration.
Meanwhile, Pompeo said during the briefing that he had discussed immigration concerns on the US-Mexico border with Pena Nieto and Andres Manuel Lopez Obrador.
US Treasury Secretary Steven Mnuchin, White House senior adviser Jared Kushner and other senior officials also participated in the discussions.
