Donald Trump unveils trade agreements with the European Union and Japan that will set baseline tariffs at 15%, with promises that they'll also invest billions of dollars in the U.S., details unspecified.

Trump said the U.S. will impose a 15% tariff on Japanese imports under the agreement, which he hailed as "maybe the largest deal in history."

That's down from the 25% levies he proposed earlier this month. Japan's prime minister says duties on autos from his nation will be cut to 15% from 25%.
