WASHINGTON (AP) — President Donald Trump is taking additional action to upset the world trade system, with plans to sign an order as soon as Wednesday that would 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 and threatening to add to already-sticky U.

President Donald Trump could announce his most sweeping tariffs yet Wednesday, unveiling reciprocal tariffs that Trump argues would level the playing field for the U.S. in global trade and would instantly become the hallmark economic policy of his nascent second term, though economists project they would increase inflation this year.
