There were proposals for permanent residency reform back in 2020 that were shelved due to online backlash. One could say that the K-Visa program which was launched last year is a pared down version and even this got a fair amount of backlash, though this time, the proposal was carried through nonetheless.
There's an article covering the responses to the 2020 proposal which lays out the discourse and rhetoric of those who oppose these sort of reforms. Bear in mind the author uses orientalizing "they have nationalists, we have patriots" language.
They also frame it as part of China's "non-democratic immigration policymaking" which somehow conceded to the popular demands of the online backlash as opposed to the "democratic" American immigration policymaking which never concedes to the popular demands of the online backlash with regards to ICE and the concentration camps. That aside, it does give an overview of what you may be looking for:
Excerpt:
The draft regulations to many seemed to fit in a tradition of the state privileging foreign nationals, at a time when domestic employment and residential conditions for many Chinese citizens are considered far from adequate. Attracting larger numbers of immigrants to aid China’s development, also sounds inappropriate to some, given China’s recent history of government-enforced family planning. Some suggest revising the regulations to eliminate any loopholes for so-called ‘low-quality’ migrants and to include guarantees that P.R. holders would not be privileged over local Chinese.
