I've just read the article you linked[1], as well as several others [2][3][4] and cannot find any information about this:
>all companies foreign or not must provide unencrypted access to data to the Chinese government and must do so in secrecy
either plainly stated or implied.
Can you provide a source for this claim? I don't doubt that this may occur, but I'd like to speak with _my own_ managers about my china & encryption concerns in an informed way.
