(CNBC) — Mexico’s former president shared some choice words for President Donald Trump, describing the American leader as a “machine” with “no compassion” while at the World Government Summit in Dubai on Sunday.

“He doesn’t seem to be a human being, he just looks like a machine, he doesn’t have any compassion,” Vicente Fox told CNBC’s Hadley Gamble.

The former leader blasted Trump’s border wall plans and focused on the divide within the U.S., adding that Trump essentially has a “f— you” approach to the rest of the world. The White House did not immediately respond to a CNBC request for comment.
