Mexican President Enrique Pena Nieto said on Wednesday night that he “regrets and disapproves” the push by U.S. President Donald Trump to build a new wall along the U.S.-Mexico border.

The new American leader issued an executive order earlier in the day aiming to speed the construction of the wall.

“I regret and reject the decision of the U.S. to build the wall,” Pena Nieto said in a video statement on Twitter. “Mexico does not believe in walls. I’ve said time and again: Mexico will not pay for any wall.”

Pena Nieto did not say whether or not he will attend a summit with Trump in Washington that the White House said would take place on Tuesday.

A senior official anonymously told The Associated Press the Pena Nieto administration “is considering” canceling the Mexican president’s visit to the U.S on January 31. “That’s what I can tell you.”
