Global cooperation is key to ensuring the security of 5G networks, cyber security officials said on Thursday at a meeting in Prague aimed at hammering out how to combat threats as nations begin rolling out next-generation telecoms equipment.

The United States has been seeking to limit the role of Chinese telecom equipment makers such as Huawei Technologies in building 5G networks due to fears they could be used by Beijing for spying. Huawei has denied the allegations.

Officials say they hope to conclude the meeting — attended by representatives from 30 European Union, NATO and countries such as the United States, Germany, Japan and Australia — with an outline of practices that could form a basis for a coordinated approach to shared security and policy measures.
