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 American-grown rice.

President Donald Trump expressed frustration with U.S.-Japan trade negotiations on Monday as Treasury Secretary Scott Bessent warned that countries could be notified of sharply higher tariffs as a July 9 deadline approaches despite good-faith negotiations.

We’ll just be sending them a letter,” Trump said, after suggesting Japan wouldn’t agree to boost U.S. rice imports.
