U.S. officials may have to curtail intelligence-sharing with Britain if it depends on Chinese telecommunications companies such as Huawei, Secretary of State Mike Pompeo said during a visit to London.

“We will only share America’s information with those networks that we are confident aren’t under the control of China or China’s government,” Pompeo told Sky News. “And so there’s real risk, if countries choose that path, that we won’t be able to participate in those networks.”
