CHINESE TELECOMMUNICATIONS giant Huawei’s global influence has been steadily growing in recent years, and the U.S. government’s concern has been growing along with it. Fearing that the spread of Chinese-made cellphones, routers and other equipment may render Western countries, including those that share the most sensitive intelligence with the United States, vulnerable to Beijing, Washington has tried to hold Huawei accountable for alleged sanctions violations and intellectual property theft — while discouraging key allies such as Britain, Australia and New Zealand from relying on Huawei technology. What’s ultimately at stake here is the future of 5G networks around the world — the ultra-fast connection systems that will soon link smartphones, enable driverless automobiles and, potentially, revolutionize warfare. Given the stakes, U.S. measures to date struck us as reasonable.
