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."

President Donald Trump says the US has agreed to a "massive" trade deal with Japan, one of the country's largest trading partners. Japan has agreed to invest $550bn (£407bn) in the US while its goods sold to America would be taxed at 15% when they reach the country - below the 25% tariff Trump had threatened.
