President Trump said the U.S. will impose 25% tariffs on Japan and South Korea, while imports from five other countries also face higher levies.

Trump delayed the "reciprocal tariffs" in April, vowing to strike roughly 90 trade deals in 90 days. So far, the White House says it has reached trade agreements with only the United Kingdom and Vietnam, as well as a preliminary accord with China.

President Donald Trump cranked up the pressure on two of America’s key trading partners, Japan and South Korea, firing off letters Monday to the heads of their countries that informed them of their new tariff rate.
