WASHINGTON: US President Joe Biden and his Mexican counterpart Andres Manuel Lopez Obrador warned of “unprecedented” pressure from migration in a call Friday that highlighted a major political headache for the White House ahead of November elections.

“In view of the unprecedented flows of migrants from throughout the hemisphere to our two countries, the presidents reiterated the need to build stronger tools for managing regional migration surges,” the White House said in a statement after the call between the two presidents.

The virtual meeting, just under an hour long, showcased Biden’s attempt to steer the complex relationship onto a more cooperative basis after the tempestuous, at times tense, situation under his predecessor Donald Trump.

“The tone of the call was very constructive. This was not a call where President Biden was threatening the Mexican president in any way,” White House Press Secretary Jen Psaki said, referring to Trump’s aggressive brinkmanship with Mexico over illegal immigration.

The two nations are inextricably tied through trade, culture and the violent narcotics industry. However, looming over everything is the quandary of how to manage both legal and illegal migration.

It’s a subject that will feature heavily at the upcoming regional Summit of the Americas in June, being hosted in Los Angeles.

“The majority of the conversation was about migration and was about continued work on coordination, on economic coordination, on taking steps to reduce migration along the border,” Psaki said.

Lopez Obrador tweeted after the call that Mexican foreign minister Marcelo Ebrard will travel to Washington on Monday to discuss “issues of cooperation for development” and the Summit of the Americas.
