The U.S Chamber of Commerce said Friday that President Trump’s call for U.S. businesses to pull out of all trade with China was the wrong course. The nation’s largest business trade association warned against any further escalation of rhetoric between the nations.

“Despite our concerns, the 40-year old trade relationship between our two countries has been for the most part productive, constructive, and mutually beneficial. U.S. companies have been ambassadors for positive changes to the Chinese economy that continue to benefit both our people,” said Myron Brilliant, the Chamber’s executive vice president and head of international affairs.
