The framing of this survey is already based on an American anglocentric cultural ideal of what it means to be "LGBTQ." When examining queer rights and identities abroad, it's essential to not fall prey to hegemonic California queer theory that posits queer liberation involves a universal "coming out" and an acceptance of specific, english identifiers in society.
As Foucault theorized, even in English society the creation of the "homosexual" as an identity, rather than act, is already a relatively recent development. There are countless cultural milieus in which queerness is performed by entirely different standards than those that are accepted by the "progressive west," and many of those cultural milieus don't revolve around a specific coming out narrative or concretized "lifestyles" arrayed by identity tag like in western english "LGBTQ" movements.
The essential markers of queer liberation are legal protections--which the PRC ensures; medical protections--which the PRC ensures; employment protections--which the PRC ensures; economic protections--which the PRC ensures; food security--which the PRC ensures; housing--which the PRC ensures; and safety--which the PRC ensures.
Now what is ensured legally and what plays out in practice are very different--for instance, though HRT is covered in many urban centres, those in smaller cities or in outlying rural provinces struggle to find doctors accepting of gender diversity. This gets worse as people come to expect specific western promises of queer liberation (that, I may add, few western nations ever deliver on themselves). The PRC is still a widely rural and socially conservative (by western standards that don't consider things like food and shelter to be socially progressive) nation, however there is direct evidence that with an improvement in economic conditions within different precincts in the PRC has come a relative increase in the social acceptance of LGBTQ family members and a diminishing of social discrimination.
Queer liberation will not come from pink imperialism, it will come from the emancipation of the impoverished masses, something the PRC is at the forefront of: since the 90s, 60% of all eradicated poverty globally has been China.
Edited to add: https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-020-08834-y here is a paper you can read specifically about the increase in queer acceptance as income increases. China isn't perfect by a long shot, but by ensuring their ability to lift the quality of life of their people, by staving off imperialist aggression, they are already doing more for queer people than most places. Is there gay marriage? No, but with increased acceptance that will likely come with time, and if I'm being honest I have a lot of negative things to say about how gay marriage was leveraged in the west to defang a much more vibrant movement for queer rights and fold a large portion of people into the status quo and away from their radical coalition with feminists attacking the institution of marriage itself.
