President Donald Trump could sign an order as soon as Wednesday to require that U.S. tariffs on imports match the tax rates charged by other countries.

Donald Trump's trade advisers were finalizing plans on Wednesday for the reciprocal tariffs the U.S. president has vowed to impose on every country that charges duties on U.S. imports, ratcheting up fears of a widening global trade war.

President Donald Trump’s desire to get even on countries by matching tariffs they have on American goods could come at a steep cost.

Which nation ultimately bears the cost of a tariff depends on what that country makes and its pull in the global market.

Existing American tariffs already restrict steel and aluminum shipments from China, which is now flooding other markets with its exports instead.

President Donald Trump on Monday imposed a 25% tariff on all steel and aluminum imports into the United States with no exceptions or exemptions.
