China Said to Plan Sweeping Shift From Foreign Technology to Own

China is aiming to purge most foreign technology from banks, the military, state-owned enterprises and key government agencies by 2020, stepping up efforts to shift to Chinese suppliers, according to people familiar with the effort.

The push comes after a test of domestic alternatives in the northeastern city of Siping that was deemed a success, said the people, who asked not to be named because the details aren’t public. Workers there replaced Microsoft Corp.’s Windows with a homegrown operating system called NeoKylin and swapped foreign servers for ones made by China’s Inspur Group Ltd., they said.
