President Trump on Monday said the U.S will impose 25% tariffs on goods from South Korea and Japan by Aug. 1, while also threatening to hit a dozen other nations with steep import duties by next month.

Trump on April 2 proposed a 20% tariff for EU goods and then threatened to raise that to 50% after negotiations did not move as fast as he would have liked, only to return to the 10% baseline. The EU has 27 member states, including France, Germany, Italy and Spain.

Donald Trump's insistence that "spoiled" Japan imports more US rice is adding to Prime Minister Shigeru Ishiba's problems ahead of elections that could sink his premiership after less than a year in office.
