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.

President Donald Trump said Tuesday that tariffs he plans to impose on South Korea are intended to “even out” what he described as an imbalance between trade and the cost of stationing U.S. troops on the peninsula.
