US President Donald Trump's vow to make Mexicans pay for a massive border wall has not only caused a diplomatic row, it has sparked patriotic fervor south of the border.

On Twitter, Facebook and Instagram, people are using the hashtag #WeAreAllMexico, punctuating anti-Trump tweets with cries of "Viva Mexico!" and boasting that they live in "the best country in the world."

President Enrique Pena Nieto's spokesman, his foreign and finance ministers, and government departments have made the country's green, white and red flag their profile photo on Twitter.

A slew of hashtags encourage Mexicans to stay away from American goods: #AdiosProductosGringos (goodbye gringo products), #AdiosStarbucks, #AdiosMcDonalds and #AdiosCocaCola.

Telecommunications magnate Carlos Slim, the world's fourth richest man, called a rare news conference to express his "great pleasure" at the burst of national pride and support for the president, even though Pena Nieto's economic reforms have chipped away at the billionaire's telephone empire.

"This is the most surprising display of national unity that I have seen in my life," Slim said, urging Mexicans to support Pena Nieto's negotiations with the US administration.
