Huawei has denied the allegations, but the Trump administration in recent months has sharply accelerated its campaign to counter the telecommunications giant’s global expansion as countries rush to lock in contracts for next-generation 5G wireless technology. The 5G tech will make it easier to connect items like cars and appliances to the internet, but it will render networks more vulnerable to cyberattacks.
Governments including Australia, Britain, Canada, Germany and Japan have all recently said they were looking closely at their telecom-equipment supply chain in the wake of the Huawei developments. Australia and New Zealand have restricted Huawei’s involvement in new 5G projects with those countries’ carriers. On Friday, London-based Vodafone Group PLC, the world’s biggest mobile carrier outside China, said it was temporarily halting purchases of some components made by Huawei, citing uncertainty over whether governments in Europe would shun the firm because of national-security concerns.
