Even with the hostile environment in the US, I suspect China is far more hostile. I don't see China retaining top talent--these individuals might simply go to Europe, Canada, Japan or elsewhere.
I've been living here for 5y and I work in a research lab. A lot of talent is deciding to stay here or come back (Chinese that went to study/work abroad).
Attracting foreign talent is a little different, but so far the government is not really worried about that.
I can only see the trend speeding up. Especially as/if the environment (air quality, etc.) improves. This now, in my personal view, seems to be the main factor for many people to decide to come or not.
