President Donald Trump has threatened to slap dozens of countries with specialized tariffs, along with taxes on imports that would affect every other nation. That could affect trillions of dollars in trade,

Critics warn his posture could embolden China to expand ties to Latin American countries, and Russia to continue advances in Ukraine.

Trump said in an Oval Office signing ceremony on Monday that his administration will impose a 25% tax on goods from Canada and Mexico that may come as soon as February 1 – a move that could raise prices for American consumers.
