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 (MSFT) Windows with a homegrown operating system 
called NeoKylin and swapped foreign servers for ones made by China's 
Inspur Group Ltd., they said.
