Ties between the United States and Mexico have deepened over 30 years of free trade, creating both benefits and irritants.

U.S. President Donald Trump is expected to sign an order on Saturday imposing hefty new tariffs of 25% on goods from Mexico and Canada and 10% on imports from China, threatening to ignite a trade war that could disrupt more than $2.

The market predicts that a 25% tariff on imports, as the White House is considering, would place Mexico on the brink of a recession.
