The American Chamber of Commerce in China has released the results of a study that provides some new insights on the impact that the coronavirus is having on its member companies, a roster of global firms that includes Boeing Co., General Motors Co., IBM Corp. and Microsoft Corp. 

Of the nearly 170 companies that participated in the survey earlier this month, 44% said they now have a negative outlook on the U.S.-China bilateral relationship as a result of uncertainty swirling around the COVID-19 outbreak.
