Don't let Huawei help set up 5G mobile networks, US warns EU nations

US officials are fanning out across Europe to warn about the security risks of allowing Chinese telecoms giant Huawei to help build 5G mobile networks, a US diplomat said Tuesday.

Washington considers the matter urgent as European Union countries prepare to roll out fifth-generation networks that will bring near-instantaneous connectivity, vast data capacity and futuristic technologies.

"We are urging folks not to rush ahead and sign contracts with untrusted suppliers from countries like China," a US State Department official told reporters in Brussels.

The official said he was meeting EU officials as well as those in Belgium, France and Germany, while colleagues will be travelling to Spain and elsewhere to underline US concerns.

"Going with an untrusted supplier like Huawei or ZTE will have all sorts of ramifications for your national security," he warned, speaking on condition of anonymity.

It could also undermine intellectual property protection, privacy and human rights, he added.

He said Washington's priority was warning Europe where strong alliances make the "national security component even more compelling from the US point of view."

In December, European Commission Vice President Andrus Ansip echoed US warnings about the threat posed by Huawei and ZTE who -- under a 2017 Chinese cybersecurity law -- are required to cooperate with Beijing's intelligence services.

Speaking on Tuesday, Ansip said the Commission, the European Union's executive arm, can play a limited coordinating role.

"National security is up to the member states," the former Estonian premier said.

"If the member states ask to coordinate, to take the common approach, then historically the Commission has always done so. We will do so if asked," Ansip said.

Huawei strenuously denies its equipment could be used for espionage. The commercial stakes are high.

Experts say Huawei is between six months and one year ahead of Sweden's Ericsson in terms of the quality of its 5G equipment.

And Finland's Nokia, is said to be even further behind.

Several operators have already begun tests in several French cities with Huawei equipment, such as France's Bouygues Telecom and SFR.

Deutsche Telekom, in an internal document obtained by Bloomberg, warned that Europe could fall behind China and the United States by as much as two years if it forgoes using Huawei's 5G equipment.

The US diplomat said Washington was motivated by security rather than commercial interests, adding that Ericsson, Nokia and Korea's Samsung would benefit from a Huawei ban -- and not US firms.
