China Threatens EU With Retaliation if It Bans Huawei Gear

China said it would retaliate against the European Union if it proceeds with a proposal to ban Huawei Technologies Co.’s equipment across the continent, escalating tensions in the long-running clash over national security and the communications company’s products.

China’s mission to the EU has asked that the commission erase language that would declare Chinese equipment a cybersecurity concern or label companies from the country as “high risk” suppliers in a proposal from Commission Executive Vice President Henna Virkkunen.
