If the US's new shiny fascist regime keeps progressing at this pace, you can bet that things will reverse quickly. Good bye, world leading startups, nobel prizes, top universities, etc. These things can happen faster than one tends to think.
The best thing countries like China could do right now is heavily open up to English, and fund things such as foreign PhD students. Everyone is fighting to get into Harvard and MIT right now, but a half decade of Trump policies could have drastic consequences a few decades down the line and give us a very different world.

People also seem to get stuck on "China" in my comment. If that makes you unhappy, replace that word with Brazil, Japan, Singapore, Estonia, whatever you want... the point is, viewed under the "startup lens", this new administration makes the dominance of the US in STEM/entrepreneurship ripe for disruption by a more nimble, flexible entity.
