FILE – The American and Chinese flags wave at Genting Snow Park ahead of the 2022 Winter Olympics, Feb. 2, 2022, in Zhangjiakou, China. The Biden administration is raising red flags about 33 Chinese companies whose legitimacy it cannot verify, imposing new restrictions on their ability to receive shipments from U.S. exporters and requiring extra diligence from American companies that want to do business with them. The Commerce Department said Monday that it was adding the companies to what is known as the “Unverified List,” a roster of businesses worldwide that are subjected to stricter export control because U.S. officials have been unable to do customary checks (AP Photo/Kiichiro Sato, File)
