Behind the upsurge in Chinese open source communities

Recently, however, China-based software companies have begun to show a greater interest in creating communities of their own. TurboLinux and Red Flag have created Whitefin and Linux-Ren, respectively. Red Flag also plans to create two additional open source communities -- UMPC (with Intel) and OpenAsianux -- before the end of this year. Why have Chinese companies suddenly changed their tunes?
