U.S. President-elect Donald Trump has threatened to sharply raise tariffs on all Chinese imports and close some loopholes Chinese exporters currently use to sell their products more cheaply in the U.S.

President-elect Donald Trump vowed additional tariffs on China as well as US neighbors Canada and Mexico, roiling markets with his first specific threat to curb global trade flows since his election win.

Mexico has supplanted China as the main source of goods, but imports keep climbing.
