Chamber of Commerce President Tom Donohue urged President Trump to back down on proposed tariffs against Chinese imports, saying the effort would do more harm than good for the U.S. economy.

“The administration is right to focus on the negative economic impact of China’s industrial policies and unfair trade practices, but the U.S. Chamber would strongly disagree with a decision to impose sweeping tariffs,” said Donohue, president of the nation’s biggest business lobby. The Chamber has long supported free-trade deals, arguing they benefit the economy overall.
