OMAHA, Nebraska (AP) — Investor Warren Buffett told thousands of Berkshire Hathaway shareholders Saturday that the United States shouldn’t use “trade as a weapon” and anger the rest of the world like President Donald Trump has done with his tariffs that roiled global markets..

“It’s a big mistake in my view when you have 7.5 billion people who don’t like you very well, and you have 300 million who are crowing about how they have done,” Buffett said as he addressed the topic on everyone’s mind at the start of the shareholders meeting.
