To be honest, China mine most of it in Inner Mongolia (a province that they kept while giving Outer Mongolia independence), and they probably think of it as a colony anyways so they are not too concern about the environmental damage. If it is near Beijing or Shanghai they'll probably think twice before doing so.
Emission control wise, if I remember right they are within a couple years of using Euro as the emission standard for vehicles. Older vehicles might get grandfathered. If I also remember right, they stop giving out moped (vespa) registration due to emission reason.
