Police in China have visited the Shanghai office of Bain Company, a U.S. consultant firm, and questioned some staff, the company said Thursday.
We can confirm that the Chinese authorities have questioned staff in our Shanghai office, Bain said in a statement.
The company said it was working closely with Chinese authorities and provided no further details.
Bain Company opened its Shanghai office in 2004 according to the company's website. Companies such as IBM also have branches in Hong Kong and Beijing.
The unannounced visit comes a month after Chinese authorities raided the Beijing office of the New York-based due diligence firm, Mintz Group, and detained five staff members.
Both of the incidents highlighted the tensions between the U.S. and China over the past few years. American companies fear that China is retaliating against U.S. firms operating in the mainland in response to actions by the Biden administration targeting Chinese tech firms in the U.S.
The American Chamber of Commerce in China has reported that U.S. firms in China are increasingly pessimistic about their prospects there. China, meanwhile, declares it welcomes foreign trade and investment but stresss that its security comes first.
FOX Business has asked the U.S. Consulate in Shanghai and the American Chamber of Commerce in Shanghai for more information.
