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 Japan and South Korea that 25% tariffs will be imposed starting Aug. 1 on goods sent to the United States.
