The main differences with the announced Chinese plan are:
* it will aggregate many various ratings and makes them available publicly on all citizens, something that's done only privately for some residents in the US
* it extends the system to social criteria, something only done privately through sports clubs, religious groups, etc in the US, and dilutes the importance of a person's financial assets in calculating a person's "worth"
* it's using technology from the ground up, intead of slowly automating a paper-based system that's already been developed over the years
So the main differences are those of degree.
