Dear XXXXXXXX,
Currently, a defnitive number is not known.
China does not have a "green card system" and only grants on average 50 permanent resident visas per year, though they are contemplating more.
There are however hundreds of thousands of temporary foreigner living and working in china.,
Also keep in mind that, like many other nations, China, to has an illegal alien problem.
There are,as reported by the U.S. State Department, and as reported by the New York Times, approximately 250,000 foreign residents in China. (does not include illegal aliens or tourisim, business visas)
