The U.S. campaign to isolate Huawei isn’t quite going according to plan. Last week, the U.K. and the EU both defied U.S. pressure by sparing the Chinese telecom giant and its state-owned counterpart, ZTE, from a blanket ban on “high-risk suppliers” of 5G gear. A week earlier, the Pentagon reportedly blocked a plan by the Commerce Department to expand a ban on sales of critical components to Chinese high-tech sectors, citing the potential costs to the United States’ own tech sector.
