Huawei Technologies Co. employees have collaborated with the Chinese military on at least 10 research projects in recent years, Bloomberg News reported Wednesday, citing research papers, indicating closer ties than the tech giant has acknowledged. The projects ranged from classifying emotions in online videos to analyzing satellite images, Bloomberg said. Huawei told Bloomberg it was not aware of its employees publishing research papers in an individual capacity, and said the company does not have any partnerships with the Chinese military. The Trump administration has said Huawei telecom equipment poses a national security risk, and has limited Huawei's ability to to business with U.S. companies.
