“I have to say that I regret (the plan), and of course, I can't agree with this American politician's position," said Nieto on Tuesday, when asked about financing the construction of the wall.
The remarks came after Trump, a billionaire real estate mogul, infuriated Mexico last June by declaring that the country was sending “criminals” and “rapists” across the border and that he would force the neighboring government to pay for a giant wall to keep illegal migrants out.
He has promised, if elected president in 2016, to expel undocumented immigrants in the United States and build a wall on the US-Mexico border.
"They say you'll never be able to build a wall," Trump said on March 2. "Well, it's 2,000 miles but we really need 1,000 miles. The Great Wall of China, built 2,000 years ago, is 13,000 miles, folks, and they didn't have Caterpillar tractors.”
Nieto compared the rhetoric of the US Republican front runner to that of German Nazi leader Adolf Hitler.
