Did you look at the demographics of graduate students in the US lately? China has now programs to revert the brain drain, offering nice jobs to successful Chinese academics in the US and elsewhere.
Just look at the attendance list of scientific conferences. You will see at least one or two Chinese names in every big international event, in pretty much any field. The ones that are held in China has more than half the attendants from China.
And they are good. They have a tradition of working hard, and there are a lot of Chinese. Once it becomes economically attractive, it is inevitable that a lot of bright Chinese people will go into research. This is already happening in my field (astrophysics) but I feel other life sciences have similar situations.
Not that I am complaining. I am looking forward to visiting Beijing next October and start new collaborations.
