Allegedly, Huawei's 5G infrastructure equipment can come with backdoors, allowing the Chinese government to spy on communications of any country using Huawei's gear.
Huawei has since committed to spending $2 billion in a drive to fix those problems, but in a letter to lawmakers last week, Ryan Ding, president of the company's carrier business group, said it would take up to five years to see results. These fears are heightened by 5G because of the sensitive information these networks will carry.
Following meetings with the European Commission and the Belgian government in Brussels, U.S. officials were also set to take a message to France, Germany, and other capitals that the world's biggest telecommunications gear maker poses a security risk, said the official, who declined to be named.
The US is concerned that if its allies continue to use Huawei kit, then America's security will be threatened. Meanwhile there have been reports the European Union is considering a de facto ban.
Last year's United Kingdom government report was written by the Huawei Cyber Security Evaluation Centre (HCSEC), which was set up in 2010 in response to concerns that BT and others' use of the firm's equipment could pose a threat.
That's why as Liu said, 'Cybersecurity should remain as a technical issue instead of an ideological issue. "Because technical issues can always be resolved through the right solutions while ideological issues cannot".
Huawei has warned that it could take up to five years to address Britain's concerns about its equipment.
He also reiterated that the company's products have never harmed national security of any country in the world. The Chinese company has been under scrutiny regarding security concerns ever since the United States encouraged its allies to bar the company from supplying 5G equipment to them.
Huawei is under increasing pressure from the States, whose government is accusing it of helping the Chinese with spying.
The Prince's Trust recently announced it would no longer accept donations from the firm, after Mr Williamson and MI6 chief Alex Younger publicly expressed their concerns over the company.
Liu will reiterate that Huawei has not and would never harm the interests of customers or countries. "Were Huawei ever to engage in malicious behavior, it would not go unnoticed - and it would certainly destroy our business".
