The Globe and Mail reports in its Tuesday edition that U.S. President Donald Trump is launching the process to impose levies on imports of semiconductors and pharmaceuticals, amid mounting uncertainty over the direction of his global trade war. The Globe's Adrian Morrow and Eric Atkins write that the Trump administration on Friday exempted smart phones, tablets and other technology products and components from 125-per-cent tariffs on China. Over the weekend, Mr. Trump and Commerce Secretary Howard Lutnick said these imports would instead be covered by a separate, planned tariff on semiconductors. Asked Monday about tariff exemptions for smart phones, the President said, "There will be maybe things coming up" and that he has had discussions with Tim Cook, the chief executive officer of Apple. "Look, I'm a very flexible person. I don't change my mind, but I'm flexible. And you have to be, you can't just have a wall," Mr. Trump said. "I don't want to hurt anybody." Pharmaceutical tariffs, meanwhile, would hammer Canadian drugmakers exporting mostly less expensive generic drugs to the U.S. American patients, who already pay some of the highest medication prices in the world, would also be affected.
