The United Kingdom has banned Huawei from its 5G telecom network, reversing a January decision to allow the embattled Chinese tech company a limited role in building the country's super-fast wireless infrastructure.
Operators such as BT and Vodafone have been given until 2027 to remove existing Huawei equipment from their 5G networks.
Making the announcement Monday, Digital and Culture Minister Oliver Dowden said new US sanctions imposed on the company in May had significantly changed the landscape.
Mr. Dowden said, given the uncertainty this creates around Huawei's supply chain, the UK can no longer be confident it will be able to guarantee the security of future Huawei 5G equipment.
The decision is a big win for the Trump administration, which has been pushing allies to exclude Huawei from their 5G networks.
Huawei has described the decision as a political one which was about U.S. trade policy and not security.
The company said it is bad for Britain and its phone users.
