The least cynical reading is that it's an expression of neo-Confucian values; those in a position of political, military or economic power have a broad belief in the importance of cooperation and "social harmony". If the NSA want to access all of Google's data, they hide an implant in a data center, put optical splitters on key fiber links or bribe a third party to provide a backdoor in a vital software dependency (PRISM and BULLRUN). If the PLA want Tencent's data or the NIS want Samsung's data they just ask for it, on the understanding that a) they're not really in a position to say no and b) cooperation with the state is a mutually beneficial quid-pro-quo.
