Well, you know, it’s not like the USA isn’t luring a lot of Chinese researchers and students already. Speaking as an American who worked as a researcher in China for almost 9 years, China is way late to the “leveraging global talent” game. They should catch up, it’s only natural.
Seems like it's much easier to leverage global talent when you are leading the research at a global level. This has arguably not been this case for (modern) china until recently.
Keep in mind that the number of foreigners in China is about the same as the number of foreigners in Tokyo.
