The UK and Germany are growing wary of allowing Huawei, the Chinese telecoms company, to install 5G equipment in their countries after a US delegation visited Europe to urge heightened vigilance against national security threats.
UK security officials on Thursday issued a new public warning to Huawei, saying the Chinese company must fix problems in the equipment it provides to British networks or risk a further deterioration in what is an increasingly strained relationship.
The clear message delivered by the US delegation this month and in online communications is that Germany and the UK as key American allies must safeguard the security of their telecoms networks and supply chains, said people familiar with the situation.
