Former Mexican President Vicente Fox doubled down on his criticism of presumptive Republican presidential nominee Donald Trump in a recent interview, comparing him to Latin American dictators and calling him a "hated gringo" while also giving him the middle finger.

Fox made the obscene gesture to Trump after appearing on the Kickass Politics podcast with host Ben Mathis. The interview was pre-recorded and released Tuesday.

"He is the ugly American," he told Mathis. “He is the hated gringo because he’s attacking all of us. He’s offending all of us.”

The former president also reiterated his criticism of Trump's proposed border wall, while comparing him to Latin American dictators Hugo Chavez and Juan Peron.

"I'm not going to pay for that f***king wall," he said.

Fox also warned if Trump starts a trade war, that Mexico could retaliate by stopping or limiting money transfers and remittance for U.S. corporations and American tourists in the country. He added that some of Trump's proposals could add not just a trade war, but a full war.

"Don’t play around with us, we can jump walls, we can swim rivers, and we can defend ourselves," he told Mathis.
