President Donald Trump said that he was likely to impose tariffs on pharmaceuticals as soon as the end of the month and that levies on semiconductors could come soon as well, suggesting that those import taxes could hit alongside broad “reciprocal” rates set for implementation on Aug.

"Other trading partners observing these threats will have the same mistrust of the negotiation process," experts argue.

Less than half of Trump 2024 voters, 46%, said they would support tariffs on China — one of America’s biggest trading partners — even if they lead to rising prices domestically. Around a third, 32%, said they would only support tariffs if they do not increase prices.
