CIA is accusing Huawei Technologies of being funded by Chinese state security, The Times said on Saturday.

The U.S. intelligence accused Huawei of receiving funding from China’s National Security Commission, the People’s Liberation Army and a third branch of the Chinese state intelligence network, the British newspaper reported, citing a source.

Earlier this year, U.S. intelligence shared its claims with other members of the Five Eyes intelligence-sharing group, which includes Britain, Australia, Canada and New Zealand, according to the report.

Huawei dismissed the allegations in a statement cited by the newspaper.

“Huawei does not comment on unsubstantiated allegations backed up by zero evidence from anonymous sources,” a Huawei representative told The Times.

The accusation comes at a time of trade tensions between Washington and Beijing and amid concerns in the United States that Huawei’s equipment could be used for espionage. The company has said the concerns are unfounded.

Another Chinese technology company, ZTE, has also been at the center of similar controversies in the United States.
