Officials from the Trump administration have described the UK’s approach to 5G security as “deeply concerning.”
Senior U.S. officials criticised the UK’s longstanding practice of testing Chinese-made equipment before deploying it in critical infrastructure, arguing that testing alone may no longer be sufficient for next-generation networks.
Chinese vendor equipment is evaluated at the Huawei Cyber Security Evaluation Centre (HCSEC) in Banbury, Oxfordshire. HCSEC had previously stated confidence that the devices posed no immediate threat, but a recent report raised worries about Huawei’s manufacturing processes and controls.
British intelligence agencies have said they believe risks associated with using Chinese 5G kit can be mitigated successfully. However, American officials argue that 5G represents a different class of risk because significant parts of the network can be changed after installation via software updates, increasing the potential attack surface.
Observers note that the U.S. push for allies to choose Western vendors may also be influenced by broader trade and geopolitical tensions with China. Reports suggest American diplomats have offered support or incentives to countries that opt for non-Chinese alternatives.
The United States has not enacted a comprehensive ban on Chinese telecom equipment domestically. U.S. operators remain free to purchase gear from vendors such as Huawei, although companies using such equipment may be ineligible for certain government contracts. As a result, some rural networks have considered using Chinese products, while many providers avoid them to prevent possible future complications.
Within the Trump administration, some advisers have urged the president to issue an order banning Chinese equipment outright; however, decisions appear linked to ongoing trade negotiations and broader diplomatic strategy.
At a recent press conference the president said: “I don’t want to block out anybody if I can help it. If there is a security issue, we don’t have a choice. It is something we will talk about, but I want fair competition.”
Last week the U.S. intensified its diplomatic campaign, taking the unusual step of warning it might curtail security cooperation with Germany if Berlin moved forward with Chinese 5G technology.
German intelligence officials briefed a parliamentary committee on Huawei, noting that “past security-relevant events” involving the company contribute to trust concerns among some policymakers.
At the European level, the European Parliament has also voiced deep concerns about Chinese 5G equipment. Chinese President Xi Jinping planned visits to Europe aimed at addressing worries over Beijing’s investments, including those in telecommunications infrastructure.
