U.S. automakers worry that President Donald Trump's agreement to tariff Japanese vehicles at 15% would put them at a competitive disadvantage, saying they will face steeper import taxes on steel, aluminum and parts than their competitors.

Japan will invest $550 billion into the U.S., and goods from the country will be subject to a 15% tariff, President Trump said. Japan has not commented on the reported deal.

U.S. President Donald Trump on Tuesday said the U.S. and Japan have struck a deal that will lower the hefty tariffs Trump had threatened to impose on goods from its Asian ally while extracting commitments for Japan to invest $550 billion US in the United States and open its markets to American goods.
