First it was Australia, New Zealand and Japan, now the US is pressing the German government to refuse to use equipment manufactured by Chinese telecom giant Huawei as Europe's largest economy seeks to build out its 5G infrastructure.

According to Bloomberg, a US delegation met on Friday with German Foreign Ministry officials in Berlin to talk about the security risks presented by Huawei's equipment, which the US says is vulnerable to spying. The meeting in Germany follows a report from late last month claiming the US had launched an "extraordinary outreach campaign" to warn its allies against using Huawei equipment (while its vulnerability to Chinese spying has been cited as the reason to avoid Huawei, it's also worth noting that the US and China are locked in a battle for who will dominate the global 5G space...a battle that Huawei is currently winning).

Germany is set to hold an auction early next year to find a supplier to help expand its 5G network. The Berlin meeting took place one day after Deutsche Telekom said it would reexamine its decision to use Huawei equipment.

US officials are optimistic that their warnings are getting a hearing, though any detailed talks are in early stages and no concrete commitments have been made, according to one of the people. The US pressure on Germany underscores increased scrutiny of Huawei as governments grapple with fears that the telecom-equipment maker’s gear is an enabler for Chinese espionage. The Berlin meeting took place a day after German carrier Deutsche Telekom AG said it will re-evaluate its purchasing strategy on Huawei, an indication that it may drop the Chinese company from its list of network suppliers.

France is also reportedly considering further restrictions after adding Huawei products to its "high alert" list. The US has already passed a ban preventing government agencies from using anything made by Huawei. But the telecoms equipment provider isn't taking these threats to its business lying down.

U.S. warnings over espionage are a delicate matter in Germany. Revelations over the scale of the National Security Agency’s signals intelligence, including reports of tapping Merkel’s mobile phone, are still fresh in Berlin five years after they came to light. Huawei is pushing back against the accusations. The company’s rotating chairman warned this week that blacklisting the Chinese company without proof will hurt the industry and disrupt the emergence of new wireless technology globally. Ken Hu, speaking at a Huawei manufacturing base in Dongguan, cited "groundless speculation," in some of the first public comments since the shock arrest of the company’s chief financial officer.

This news will likely not go over well in Beijing, which is still struggling with the US and Canada over the arrest of Huawei CFO Meng Wanzhou in Vancouver. In an editorial published Sunday, the Global Times, an English-language mouthpiece for the Communist Party, warned that China should retaliate against any country that - like Australia - takes a hard line against Huawei. So, if you're a German citizen in Beijing, you might want to consider getting the hell out of Dodge.
