Several employees of Huawei Technologies have cooperated with members of the Chinese armed forces in at least 10 research projects over the past 10 years, Bloomberg said Thursday.
Huawei's employees have cooperated with members of various PLA units in projects ranging from artificial intelligence to wireless communications, the agency said.
The research projects are part of a few of the studies that have been uncovered, she said, adding that she collected information from published journals and electronic databases used by Chinese academics and industry specialists.
"Huawei has no cooperation or research and development partnership with the PLA institutions," said Glen Sloch, a spokesman for the Chinese company.
"The company develops and produces only communications devices that comply with civilian standards worldwide, and does not modify products related to research and development for the military."
Huawei has been under scrutiny for more than a year, led by US allegations that "rear doors" with routers, adapters and other devices could allow China to spy on US communications, but Huawei has repeatedly denied that its products pose a security threat.
The US government banned its agencies last month from buying Huawei's communications equipment and imposed strict restrictions on US companies with Huawei.
