US Secretary of State Mike Pompeo also told a news conference on Wednesday that plans were being finalised to cut down data theft by the Chinese video stream app TikTok, though he did not say it would be banned.
Pompeo's announcement came a day after the British Government said it would be getting rid of Huawei gear in its networks by the end of 2027.
He told a questioner that the US was happy with the UK decision.
"You suggested they did this because of US sanctions. I don’t actually think that’s true. I actually think they did this because their security teams came to the same conclusion that ours have, is that you can’t protect this information.
"This information that transits across these untrusted networks that are of Chinese origin will almost certainly end up in the hands of the Chinese Communist Party. And so I think they did this for the right reasons.
"I think they did this to protect and preserve and secure the freedoms of the people of the UK and I’m confident they’ll continue in that policy."
