President-elect Trump has promised to impose 25% tariffs on all goods imported from Canada and Mexico, and tariffs as high as 60% on goods coming from China on day one of his new administration. What will these protectionist policies accomplish?

President-elect Donald Trump has vowed to impose import tariffs on products entering the United States from Mexico, Canada and China, starting on his first day in office.
