This continues to hinder the
country's meaningful development because foreign talent avoids innovating alongside
China's brilliant minds in the country, even in Shanghai!

Sorry, must disagree:

International Cooperation in Science and Technology

China has cooperated through programs in science and technology with 152 countries and regions, signed inter-governmental sci-tech cooperation agreements with 96 countries and joined more than 1,000 international sci-tech cooperation organizations. Non-governmental international cooperation and exchanges have also been increasing. The China Association for Science and Technology and affiliated organizations have joined 244 international scientific and technological organizations; in international scientific and technological organizations, Chinese researchers hold 293 executive member-director or higher level posts, 281 leading posts on expert committees of international organizations; and 253 CAS scientists hold posts in international scientific organizations. The China Natural Science Foundation concluded cooperative agreements and memoranda with counterpart organizations in 36 countries.

I imagine that at least a few of the above mentioned scientists and researchers haven't minded rubbing elbows with the Chinese in Shanghai or almost any other Chinese city you may mention. Moreover, I would also guess that most of those who have done so considered it an honor and a privilege.

China is a non-immigration country,
which is contrary to the attitude of many ordinary Chinese.

Again, sorry to disagree. You may find the following article to your interest:

The Chinese govt has a lot to learn!

Don't we all, though - don't we all? Since returning to America, after seven years in China, it has astounded me how little is actually known about China and how little they want to know. What is "known" is rarely regarded as speculation, but instead regarded as "truth." Such is the world we live in. That is, a world where we are spoon fed information by the media while they are guilty themselves, so often, of regurgitating that which can only be consumed by those who willingly accept it without digging deeper. Fortunately, in this age of Trumpism, we see the media aligning itself with the will of the people in ever increasing numbers. Nevertheless:

So, nope, not arguing - just sayin.'
