US President-elect Joe Biden, on Saturday, told Mexican President Andres Manuel Lopez Obrador that he was committed to addressing the root causes of poor Latino migrants crossing the border into America, reported news agency AFP.

In an attempt to curb the dangerous flow of people entering the US from Mexico and Central America, outgoing President Donald Trump tightened the southern frontier, including his fitful plan to build a border wall.

Biden spoke Saturday with President Andres Manuel Lopez Obrador and emphasised “the need to reinvigorate US-Mexico cooperation to ensure safe and orderly migration,” the Biden transition team said in a statement.

“The two leaders noted a shared desire to address the root causes of migration in El Salvador, Guatemala, Honduras, and southern Mexico and to build a future of greater opportunity and security for the region,” the team said.

The border is a major crossing point for migrants fleeing poverty, drug-related violence and other woes in Mexico and Central America.

Lopez Obrador, a leftist, had cordial relations with Trump but it was only this week that he finally congratulated Biden on his win in the November 3 US election.
