Mexico is to consider a proposal to revoke its treaties with the US, including the 1848 agreement that transferred half its territory to Washington if Donald Trump is elected and tries to make the US's southern neighbour pay for a border wall.
A Mexican senator is due on Tuesday to propose legislation that would empower the government to retaliate of Mr Trump inflicts expropriations or economic losses on his country to make it pay for a wall along the 2,000 mile border.
Reuters said that Armando Rios Piter, an opposition senator for the centre-left Party of the Democratic Revolution (PRD), hoped his initiative would protect Mexicans, and highlight the risks of targeting them economically.
"In cases where the property/assets of (our) fellow citizens or companies are affected by a foreign government, as Donald Trump has threatened, the Mexican government should proportionally expropriate assets and properties of foreigners from that countryon our territory," says his proposal.
Total remittances to Mexico from abroad ‐ most of which come from the United States ‐ were worth nearly $25bn (£18.6bn) last year, according to the central bank. Bilateral trade between the two nations is worth about half a trillion dollars a year.
Mr Trump stormed to victory in the Republican primary with strident and frequently offensive comments about migrants from Mexico and other Central American countries. He vowed to build a wall, force Mexico to pay for it, and deport up to 11 million undocumented migrants.
