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

This time, it's BT that's triaging the Chinese telecoms company from its 4G network infrastructure within the next two years.

The last time HEXUS reported on concerns about Chinese owned Huawei and ZTE was back in 2012, when the U.S. government and USA companies were urged to stop participating in projects with these companies due as the "pose a significant threat to national security".

"As a result, Huawei have not been included in vendor selection for our 5G core", a spokesperson said in an emailed statement.

Huawei, founded by a former People's Liberation Army officer, has already been excluded from the roll-out of 5G networks in the US, New Zealand and Australia after questions were raised about the firm's links to the Chinese state.

"We're applying these same principles to our current request for proposal for 5G core infrastructure".

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

In a statement reproduced by The Guardian, BT said that it started replacing Huawei equipment after acquiring EE in 2016, following principles it set out as far back as 2006.

Huawei and EE had in November 2017 also demonstrated separate uplink-downlink (UL/DL) decoupling technology across a 5G-LTE network deployment in London. Huawei's "enhanced packet core" technology is still at the core of EE's 4G network today.

In their own statement, the company said: "Huawei has been working with BT for nearly 15 years".

Its decision not to use the Chinese firm for its "core" services came the following year.

The US, Australia and New Zealand have all moved to bar Huawei's equipment from 5G networks, and the head of the UK's secret service, Alex Younger, warned this week that the United Kingdom must decide whether to do the same.

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.

The report said the Chinese government could force companies to make products perform below expectations, facilitate "state or corporate espionage" or compromise the confidentiality of networks using them.
