Explainer: As Britain decides, Europe grapples with Huawei conundrum

Britain decided Tuesday to let Chinese tech giant Huawei have a limited role supplying new high-speed network equipment to wireless carriers, ignoring the U.S. government's warnings that it would sever intelligence sharing if the company was not banned.

Britain's decision is the first by a major U.S. ally in Europe, and follows intense lobbying from the Trump administration and China as the two vie for technological dominance.

It sets up a diplomatic clash with the Americans, who claim that British sovereignty is at risk because the company could give the Chinese government access to data, an allegation Huawei denies.
