Pompeo spoke with Videgaray on August 8 and the two leaders talked about the importance of reducing irregular migration through Mexico and the region and discussed the need for greater investment in Central America to address security, governance, and economic prosperity challenges, spokesperson Heather Nauert said.
After a second day of meetings with US Trade Representative Robert Lighthizer in Washington, Guajardo said talks were "advancing" but that it was not clear how long it would take to settle US-Mexico issues before Canada would come back to talks.
The negotiations stalled due to Trump's favour for a sunset clause in USA trade agreements, requiring parties to renew them every five years.
"We are organizing the items according to the degree of complexity and sunset clause is the very last", he said.
Asked if Canada would rejoin the NAFTA talks next week, Guajardo said, "Hopefully".
"It benefits the United States to continue being a major ally of Mexico, as a neighbor and as a regional economy, which combined makes us the most powerful in the world", he said.
But there is no specific date to return to trilateral discussions, he said.
Mexico's President-elect Andres Manuel Lopez Obrador has vowed that his country would not be threatened by a wall.
"We're glad Mexico and the USA continue to work out their bilateral issues".
