The Times reports that documents disclosed by Edward Snowden show: "The agency pried its way into the servers in Huawei’s sealed headquarters in Shenzhen, China’s industrial heart. . . One of the goals of the operation, code-named 'Shotgiant,' was to find any links between Huawei and the People’s Liberation Army, one 2010 document made clear. But the plans went further: to exploit Huawei’s technology so that when the company sold equipment to other countries — including both allies and nations that avoid buying American products — the N.S.A. could roam through their computer and telephone networks to conduct surveillance and, if ordered by the president, offensive cyberoperations."
