Berlin   -   Germany said Thursday it will phase out the use of components from Chinese telecom giants Huawei and ZTE in its 5G networks in the coming years due to national security concerns. It was the latest move by Berlin to reduce economic reliance on Beijing that some fear have left it vulnerable, and follows warnings from the EU that the firms pose a risk to the bloc. Parts from Huawei and ZTE will no longer be used in “core” 5G mobile networks by the end of 2026 at the latest, the interior ministry in Berlin said.   In 5G access and transmission infrastructure, the systems of the telecom firms must be replaced by the end of 2029.

“We are protecting the central nervous systems of Germany as a business location -- and we are protecting the communication of citizens, companies and the state,” said Interior Minister Nancy Faeser. “We must reduce security risks and, unlike in the past, avoid one-sided dependencies.”

The ministry said that 5G networks form part of Germany’s “critical infrastructure” and are important for the functioning of sectors ranging from health to transport and energy.

Telecoms networks must be protected from cyberattacks, which could be an “existential threat”, it added.

Officials have reached agreements with Germany’s 5G network operators, Deutsche Telekom, Vodafone and Telefonica, on banning Huawei and ZTE. Government sources had already indicated in September last year that Berlin was considering such a move, although the dates announced are later than those originally envisaged to give companies time to adopt the new measures.

Faeser would not be drawn on whether she feared retaliatory measures from China, although she said that Beijing had been informed about the bans. “For me, as interior minister, it is a matter of finding regulations for telecommunications networks, for critical infrastructure, and I have done that,” she told a press conference.

In response to the ban, Huawei insisted there was “no specific evidence” that the firm’s “technology has cyber security risks”. “Huawei has developed into a continuously innovative, secure, and reliable telecom equipment supplier in the German market,” a spokesperson said. Beijing’s embassy in Berlin also said the move was driven by “groundless accusations”.

“There is no evidence indicating that these Chinese companies are a danger to any country,” the embassy said, according to state news agency Xinhua.

“Whether Germany can handle this issue fairly and justly will be a touchstone for its own business environment,” it added.
