EXPLAINER: Mexico confronts complex position on immigration

Mexico is facing immigration pressures from the north, south and within its own borders, putting it in an increasingly difficult position

MEXICO CITY -- Mexico has faced immigration pressures from the north, south and within its own borders in recent weeks, putting it in an increasingly difficult position. Thousands of migrants continue to cross its southern border, the United States sends thousands more back from the north and there's the renewed prospect of the U.S. making asylum seekers wait in Mexico for long periods of time. President Andrés Manuel López Obrador said Thursday the strategy of containing migrants in the south was untenable on its own and more investment is needed in the region to keep Central Americans from leaving their homes. But the groups of migrants walking north from southern Mexico in recent days have mostly been Haitians, a group that would not be addressed by the president's proposed tree planting and youth employment programs in Central America.
