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.

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.

President Donald Trump unveiled a wave of letters again threatening key trading partners with high tariff rates even as he delayed the increased duties until Aug. 1 and suggested that he was still open to negotiations.
