On Tuesday, British Prime Minister Boris Johnson ordered Huawei equipment to be completely purged from Britain's 5G network by the end of 2027.
The Chinese telecoms giant's UK spokesman Ed Brewster said London had reacted to pressure from Washington rather than security concerns.
The Huawei official blasted the move as "disappointing," saying, "Regrettably, our future in the UK has become politicized, this is about US trade policy, not security."
China's ambassador to Britain Liu Xiaoming also denounced the decision as "disappointing and wrong,” saying, "It has become questionable whether the UK can provide an open, fair and non-discriminatory business environment for companies from other countries.”
The ban comes nearly two weeks after London described Huawei as a potentially hostile state vendor. Beijing has warned to retaliate, threatening to open a new front in the China-UK rift.

Meanwhile, the United States praised Britain's decision on Tuesday to order the phased removal of Huawei from its 5G network.
"We welcome news that the United Kingdom plans to ban Huawei from future 5G networks and phase out untrusted Huawei equipment from existing networks," Secretary of State Mike Pompeo said in a statement.
"We will continue to work with our British friends on fostering a secure and vibrant 5G ecosystem, which is critical to transatlantic security and prosperity," he said.
