Losses in Chinese tech stocks outpaced their U.S. counterparts on Thursday, with those losses holding into the close after President Donald Trump announced tariffs on tens of billions of dollars’ worth of goods from China.
On Thursday, Trump said he instructed the office of the U.S. Trade Representative to draw up a list of tariffs on Chinese products totaling at least $50 billion with an emphasis on sensitive technologies.
The subject of Chinese tariffs has rattled markets in recent days on fears that they will trigger a trade war with the world’s second-largest economy. U.S. trade groups recently urged Trump to halt the tariff plan, warning that it would trigger a chain reaction of negative consequences for the U.S. economy.
