WASHINGTON — President Donald Trump says he is not planning to extend a 90-day pause on tariffs on most nations beyond July 9, when the negotiating period he set would expire, and his administration will notify countries that the trade penalties will take effect unless there are deals with the United States.

President Donald Trump said that although trade negotiations are still ongoing, he would rather send countries a letter that lays out the tariff rates they face and not extend the July 9 deadline, when the halt on his “reciprocal tariffs” will expire.
