President Trump has dropped his threat to impose tariffs on Mexico after it agreed to prevent more migrants from entering the United States. A joint declaration said Mexico would take unprecedented steps to curb illegal immigration. Here's Chris Buckler.

A key part of this deal is something that Mexico had been resisting and that was about the whole issue of people claiming asylum in the US. Because up to now, they cross over into the US to claim the asylum and what Americans wanted to do is essentially return them to Mexico while they wait for the cases to be heard. 

Mexico had resisted that and resisted that again, but now in this deal, they say they will allow them to be returned to Mexico and they'll actually give them access to jobs, health care and education while they wait in the country. Now from the US point of view, that is a big commitment and a big change to what Mexico have been doing there. I think President Trump will regard that as a win.
