Mexican President Andres Manuel Lopez Obrador said on Friday his government will reinforce measures to contain migration as he seeks to help the United States cope with record numbers of people trying to reach the US border. Lopez Obrador's comments come a day after he spoke with US President Joe Biden, during which both agreed that more enforcement was needed at their shared frontier, as record numbers of migrants disrupt border trade. "What was agreed is that we keep working together," Lopez Obrador told a regular press conference.
