Great Walls of the United States and Mexico
"This morning we informed the White House that I will not attend the business meeting scheduled for next Tuesday with the @POTUS," Nieto tweeted.
Trump tweeted earlier Thursday that if Mexico refused to pay for the wall it might be best to scrap their upcoming meeting.
"The U.S. has a 60 billion dollar trade deficit with Mexico. It has been a one-sided deal from the beginning of NAFTA with massive numbers...," Trump tweeted. "If Mexico is unwilling to pay for the badly needed wall, then it would be better to cancel the upcoming meeting."
