I think people who think China can be contained are being naive. As an academic, I am extremely impressed with the improvement in scientific publications in CS out of China of late. In 10 years, they are now killing it on a consistent basis (personal anecdote: a paper from Tsinghua or Shanghai Jiao Tong on average is as good as one from Berkeley, Stanford or MIT). I have a feeling it has to do with the reality that Chinese nationals (or people with some ethnic/language connection) are an integral part of cutting edge science globally. It is extremely do-able to entice these individuals back. Western countries have severely under invested in research .. even back when I got my PhD (like a decade ago), my job packages were far superior in Asia (not just China) than in the West.
I think in 5G, some top level planners in the West have realized the error of their ways, and are investing heavily in basic research. I think it is too late.
Also, only one of them has anything to do with theft. The other two are simply unrelated news stories about people with links to China - one was a US researcher who may have lied to get a visa, the other simply a "policy breach".
To cite them here is firstly to lie, as they aren't relevant, but secondly to show some pretty xenophobic tendencies, equating any news story connected to anyone Chinese as being proof of some other anti-Chinese theory.
