Haven't checked in detail but i think its still a grey area and not sure if its implemented to full extent for private sector yet. Also there is/will be DTA to avoid double taxation depending on residence status in the long run so most likely won't be any different from expats coming from other parts of the world!!
BTW, China is good at making first-copy of everything US/World does, isn't it!!!
