The European Union have unveiled security guidelines for next generation high-speed wireless networks that stop short of calling for a ban on Huawei, in the latest setback for the US campaign against the Chinese tech company.
The EU's Executive Commission on Wednesday outlined a set of strategic and technical measures aimed at reducing cybersecurity risks from fifth-generation, or 5G, mobile networks.
The recommendations include blocking high-risk equipment suppliers from "critical and sensitive" parts of the network, including the core, which keeps track of data and authenticates smartphones connecting to cells.
No companies were mentioned by name but the term "high risk" supplier was an obvious reference to Huawei, the world's top maker of networking gear such as switches and antennas.
The guidance in the EU's "toolbox" for 5G is aimed at helping national governments handle the technical challenges and geopolitical controversy involving Huawei as they prepare to build new telecom infrastructure costing billions of dollars. But it will be up to individual countries to decide what kind of role Huawei will play.
"As many critical services will depend on 5G, ensuring the security of our networks is of high strategic importance for the entire European Union," the EU's executive vice president overseeing digital strategy, Margrethe Vestager, said at a press briefing in Brussels.
The US has been lobbying European allies to ban Huawei, over concerns it could be compelled to help with electronic eavesdropping after Beijing enacted a 2017 national intelligence law.
US officials have repeatedly warned they would have to reconsider intelligence sharing with allies that use Huawei. The company has denied the allegations.
The measures are similar to those taken a day earlier by Britain, which also opted not to introduce an outright ban on Huawei, instead prohibiting it from supplying equipment used in the core, while limiting its role supplying antennas and base stations for the less sensitive "radio access network."
