> China welcomes all skilled foreign talent to come work and take residence in the country with open arms.

This just isn't true. There's a K visa for young STEM professionals, which is about a year old. It's a bit more flexible for this very narrow group, otherwise you need a Z visa and work permit. You need a job first before the provincial labor authorities will approve a work permit. There's a points system, salary requirements and age cap.

There's no practical path to permanent residence in China. The Chinese "green card" equivalent has been issued to under 15,000 people since 2004. Even under Trump, the US issues about 10x more green cards in a single year than China has in two decades.

The numbers don't lie: in a country of over a billion people, there are well under 1 million foreign workers. There's a massive problem with youth underemployment and unemployment and net migration has been negative for 75+ years.
