Former Mexican President Felipe Calderón says his country will not pay "a single cent" to build Donald TrumpDonald TrumpThe Memo: The Obamas unbound, on race Iran says onus is on US to rejoin nuclear deal on third anniversary of withdrawal Assaults on Roe v Wade increasing MORE's proposed wall on the border.

“Mexican people, we are not going to pay any single cent for such a stupid wall!” Calderón told CNBC on Saturday. “And it’s going to be completely useless.” 


 Calderón, who served as president from 2006 to 2012, said Trump is “not [a] very well-informed man.” 

“The first loser of such a policy would be the United States,” he added. “If this guy pretends that closing the borders to anywhere either for trade [or] for people is going to provide prosperity to the United State, he is completely crazy.” 

This is not the first time Mexico has said it would not help pay for the Republican presidential contender's proposed wall.

Eduardo Sánchez, a spokesman for Mexican President Enrique Peña Nieto, said in August that the country was not taking Trump’s comments seriously. 

Trump has been insisting for months that if elected to the White House he will build a wall along the Mexico-U.S. border and make Mexico pay for it.
