REUTERS/Aly Song/File PhotoJan 30 (Reuters) - The Biden administration has stopped approving licenses for U.S. companies to export most items to China's Huawei, according to three people familiar with the matter. Qualcomm Inc (QCOM.O) in 2020 received permission to sell 4G smartphone chips to Huawei. Licenses for 4G chips that could not be used for 5g, which might have been approved earlier, were being denied, the person said. American officials placed Huawei on a trade blacklist in 2019 restricting most U.S. suppliers from shipping goods and technology to the company unless they were granted licenses. But U.S. officials granted licenses that allowed Huawei to receive some products.
