The UK is reconsidering its decision to give Huawei equipment a limited role within the country's 5G network.
The intention to re-evaluate the decision was revealed shortly after the USA imposed sanctions on the company, as it seeks to prevent computer chips based on American designs from being used in Huawei equipment.
A spokesperson for the UK's National Cyber Security Centre told Sky News: "Following the US announcement of additional sanctions against Huawei, the NCSC is looking carefully at any impact they could have to the UK's networks."
Prior to that, the Security Centre insisted it was capable of managing the risks that come with using Huawei equipment.
In January, the UK announced Huawei would be allowed to play a limited role in its 5G network.
Defending the decision, UK Culture Secretary Baroness Morgan said: "This is a UK-specific solution for UK-specific reasons and the decision deals with the challenges we face right now.
"It not only paves the way for secure and resilient networks, with our sovereignty over data protected, but it also builds on our strategy to develop a diversity of suppliers.
"We can now move forward and seize the huge opportunities of 21st-century technology."
