Doubt it's a Pantsir copy. PLA doesn't operate any Pantsirs and have not bought any. So if anything it's another short range air defence system. You can't copy what potentially makes a system more effective without owning it, operating it, and understanding it. I don't think the Pantsir is special in any way. The equipment isn't infallible, the missiles are groundbreaking but they are certainly better than what everyone else has for short ranges (two staged and probably more optimised performance). It's just a good modern gun + missiles combo all mobile unit complete with all the sensors required to perform AD.
PL-10 SAM is way too antiquated and a crappy missile even by past standards. HQ-7 is decent but a modernised short range AD that could serve in a similar role as Pantsir does, would probably need to be based off more modern missiles. There is the ground based PL-12 and extended range missile. There's the "new" triple 5 missile for the navy but all of those are more mid range and bulkier. I can see an HQ-7 replacement be based on a new missile. Possibly one that is two staged and cheap enough to manufacture in numbers like Pantsir's. That's the only part I suppose would be following Pantsir.
