Mexican President Andres Manuel Lopez Obrador on Thursday used a climate change summit to tell US President Joe Biden that force will never solve the issue of mass migration.

Lopez Obrador said people moving north to the United States in search of better lives at a time of climate change are "exceptional people" and that new policies are needed to address the growing movement.

"The migration phenomenon, as we all are aware of, is not going to be solved by force," he said.
