President Trump said the U.S. will impose steep levies on imports from 14 countries starting next month, heightening pressure on trading partners.

Many countries thought they were negotiating in good faith. The White House renewed its “reciprocal” tariff plan anyway, giving countries until Aug. 1 to make offers.

President Donald Trump on July 7 threatened to impose 25 percent tariffs on Japan and South Korea, and levies as high as 40 percent on 12 other countries, if they did not reach a deal by August 1.
