U.S. President Donald Trump said on Tuesday South Korea should be paying for its own military protection and suggested the U.S. ally needed to pay more for the U.S. troop presence there, a day after saying he planned to impose a 25 percent tariff on its imports.

The country’s new president, in office for a little over a month, had just dispatched his senior deputies to Washington to try to work out a trade deal.

President Donald Trump on Monday informed 14 nations, including Japan and South Korea, that new tariffs of at least 25% will be imposed starting Aug. 1 on most goods sent to the United States.
