Japan has reported its exports fell in May as shipments of autos to the U.S. dropped nearly 25% from a year earlier due to higher tariffs imposed by President Donald Trump.

Japan's top trade negotiator Ryosei Akazawa said on Friday that trade negotiations with the U.S. "remained in a fog" despite efforts by both sides to seek an agreement.

TOKYO—Japan’s exports declined for the first time in eight months in May, highlighting the impact of President Trump’s tariffs. Exports, a main engine of growth for Japan’s economy, fell 1.7% in May from a year earlier.
