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.

While South Korean imports to the U.S. face 25% tariffs, the same as Trump promised in April, the rate on Japan has been raised by 1 percentage point to 25%.
