China accuses Britain of helping Washington hurt Chinese tech giant Huawei

China accused Britain on Wednesday of colluding with Washington to hurt Huawei after the Chinese tech giant was blocked from working on a British next-generation mobile phone network.

A government spokeswoman said Beijing will protect Chinese companies but gave no indication of possible retaliation.

Washington accuses Huawei Technologies Ltd., the biggest maker of switching gear for phone and internet companies, of being a security risk, which the Chinese company denies. The Trump administration wants European and other allies to exclude Huawei as they upgrade to fifth-generation, or 5G, networks.

On Tuesday, the British government announced Huawei would be excluded from work on the network because U.S. sanctions made it impossible to ensure the security of Chinese-supplied equipment.

“Without any concrete evidence, the United Kingdom took unfounded risks as an excuse and cooperated with the United States to discriminate, suppress and exclude Chinese companies,” foreign ministry spokeswoman Hua Chunying said.

Last year, Washington imposed curbs on Huawei’s access to American components and other technology. In May, the Trump administration tightened controls by blocking non-U.S. companies from using American technology to produce processor chips and other components for Huawei without Washington’s approval.

Chinese officials accuse Washington of misusing national security concerns to block a rising competitor to U.S. tech suppliers.

“China will fully and seriously evaluate this incident and take all measures to safeguard the legitimate rights and interests of Chinese enterprises,” Hua said.

On Tuesday, President Donald Trump said Washington told other governments to avoid Huawei “if they want to do business with us.”

“We convinced many countries — many countries — and I did this myself, for the most part, not to use Huawei because we think it’s an unsafe security risk,” Trump said in Washington. “I talked many countries out of using it. If they want to do business with us, they can’t use it.”

Huawei is at the center of U.S.-Chinese conflicts over technology development and possible spying. The company’s chief financial officer is under house arrest in Canada and fighting extradition to the United States to face charges related to possible violations of trade sanctions on Iran.
