Britain in Huawei Dilemma as China Relations Sour Henry Ridgwell LONDON - There is growing speculation that Britain may be about to reverse course and ban Chinese firm Huawei fromBritain'srollout of 5G mobile telecoms technology. Prime Minister Boris Johnson approved Huawei's involvement in the constructionof non-core elements of Britain's 5G mobile network in January. The United States strongly criticized that decision, warning that the company is closely linked to the Chinese government and poses a big security risk. It appears Johnson may be about to heed that warning. "I am very, very determined to get broadband into every part of this country, reaching out for across the whole of the U.K. And we're convinced that we can do that,"Johnson told reporters Monday. "I am also determined that the U.K. should not be in anyway be vulnerable to high-risk state vendors. So,we'll have to think carefully about how we handle that. We'll have to come up with the right technological solutions." So,what has changed? In May,the United States imposed sanctions preventing U.S. companies from supplying Huawei with crucial microchips used in 5G technology. Britain's National Cyber SecurityCenter, part of the intelligence services, has since warned that the U.S. move makes Huawei technology less secure and reliable. .
