Britain's BT joins global ban on China's Huawei

There are fears the Chinese telecom giant could pose a security risk

Britain's largest mobile provider revealed on Wednesday it was removing the equipment of China's telecoms giant Huawei from its 4G cellular network.

BT's announcement comes with Washington reportedly pushing its allies to shun Huawei technology as they roll out next-generation 5G networks.

The move also comes after the head of MI6 foreign intelligence service this week singled out the Chinese company as a potential security risk.

Huawei - one of the world's largest mobile equipment and service providers - has long been under scrutiny over its allegedly close ties to China's state intelligence services.

Both Beijing and the company deny the charge.

BT said it has been in the process of removing Huawei equipment from instrumental parts of its 3G and 4G mobile networks since 2016.

It said in a statement that the decision was made "as part of network architecture principles in place since 2006".

"We're applying these same principles to our current RFP (request for proposal) for 5G core infrastructure," the British group added.

"As a result, Huawei have not been included in vendor selection for our 5G core."

The Wall Street Journal reported last month that Washington has asked its allies to cut ties with Huawei because its equipment posed strong cyber security risks.

The push is forcing companies and governments to finely balance their positions because of the enormous political and economic influence of both Washington and Beijing.

New Zealand's government last week insisted that it was not banning Huawei from its 5G network rollout because it was Chinese.

"It's not about the country, it's not even particularly about the company, it's about the technology that is proposed," New Zealand's intelligence agency minister Andrew Little said.

BT likewise stressed that "Huawei remains an important equipment provider outside the core network, and a valued innovation partner."

The Wall Street Journal said the UK government is currently reviewing the makeup of its telecommunications equipment market.

Britain's MI6 head Alex Younger publicly questioned on Monday whether Huawei should be involved in the 5G platform.

"We need to decide the extent to which we are going to be comfortable with Chinese ownership of these technologies and these platforms in an environment where some of our allies have taken a very definite position," he said in a rare public address.

He said a report by a security committee of the US Congress has concluded that China could exert sufficient pressure on companies such as Huawei to achieve strategic security goals.

Beijing could "force Chinese suppliers or manufacturers to modify products to perform below expectations or fail, facilitate state or corporate espionage, or otherwise compromise the confidentiality, integrity, or availability," Younger said.

BT used to be known as British Telecom - the government-run provider of fixed line services in the United Kingdom.

It changed its name and was privatised between 1991 and 1993. BT reports offering various services in around 180 countries.
