Whether it's a BAT or a tariff, the president's promise of a wall paid for by Mexico is not something Mexico's President Enrique Peña Nieto says he is willing to entertain.
Mr. Trump said he wanted to build an "impenetrable, physical, tall, powerful, beautiful, southern border wall" between the USA and Mexico.
"With respect to the payment for the border wall, both presidents recognised their clear and very public difference between their stances on this very sensitive issue", according to a statement from the Mexican president's office reported by the New York Times.
"The presidents also agreed for now to not talk publicly about this controversial issue". "I love the Mexican people".
His signature policy prescription was to build a wall across the 3,200-kilometer border between the United States and Mexico.
"I asked our Mexican brothers to look further south and we can all go after our hopes together, with our Latin American and Caribbean identity, we are a great family", he said.
Finally, the threat of terrorists crossing into the United States from Mexico must be taken seriously, however once again we must soberly consider why they may seek to do us harm.
He said businesses should not be too anxious if Trump's policies led to the collapse of the North American Free Trade Agreement (NAFTA) underpinning Mexico's economy, saying the country could fall back on WTO tariffs.

Another major source of Mexican imports are appliances, including refrigerators, air conditioners and centrifuges.

One of the proposals to pay for the wall involves a 20 percent border tax on imports from Mexico.

Pena Nieto said he would wait for a report from a high-level Mexican delegation holding meetings in the USA capital this week and consult with governors and lawmakers before deciding on "the next steps to take".
