Mexican President Enrique Peña Nieto announced on Thursday that he will not attend a meeting with President Donald Trump originally planned for Jan. 31.

“We have informed the White House this morning that I will not go to the working meeting planned for next Tuesday with @POTUS,” Peña Nieto posted on Twitter in Spanish. “Mexico reiterates its good will to work with the United States to reach agreements favorable to both nations.”

White House press secretary Sean Spicer told reporters on Thursday that Trump’s administration “will look for a date to schedule something in the future” and “keep the lines of communication open,” per a pool report.

Trump signaled Thursday morning that he was considering canceling the meeting with Peña Nieto after the Mexican president refused, again, to pay for Trump’s proposed border wall.
