Chinese EVs are more technicly advanced than Western EVs.

That is a somewhat broad claim that needs decomposing. I would agree that Chinese EV industry is quite more advanced in terms of manufacturing processes and cost optimization, but that is not "technically" more advanced per se, its just a reflection of a culture. Maybe the salt batteries will be a breakthrough, but at least for me it has been difficult finding reliable data on it; Other than that, afaik (and from a layman perspective) there isn't anything inherently superior in chinese EV vehicles from a technological perspective, when compared to western counterparts. Cheaper, yes. But thats about it.
