Japanese carmakers have largely absorbed the cost of US President Donald Trump’s tariffs on auto imports, a move that may undermine the Asian nation’s negotiating power ahead of a July 9 deadline that will see duties rocket even higher.

President Donald Trump is threatening to impose higher tariffs on Japanese exports to the United States over what he claims is the country’s unwillingness to buy rice from here.

US President Donald Trump has threatened to impose a "30% or 35%" tariff on Japan if a deal between the two countries is not reached before a deadline next week. That would be well above the 24% tariff Japan was hit with as part of Trump's so-called "Liberation Day" on 2 April, when he announced steep import duties on countries around the world.
