I am sure China will relax its travel, qurantine, restriction policies etc, including the visa policy. Things cannot stay the same.
The issue is timing and to the degree the policy will change. There are many expats and locals who build and invest their careers on globalization and China being big part of globalization.
Unfortinately time is not infinite, people have obligations and responsibilities to themselves and families, and also not many have 3 to 5 years ( we are already in year 3 of Covid)to wait around to let their career and businesses sitting in uncertainty. I am sure things wiell recover eventually (geopolitics permitting), but I have to move on instead of waiting. I will be happy to see everyone who has invested in their career in China prosper once it is all over and see geopolitics is not longer an issue on a long term. My best wishes to everyone in this thread who all have stakes in China,
