Pac-3 isnt specialized for ABM but it can attempt it. But if hq-20 is just better than hq-22 than I dont see why notIs it confirmed, that the HQ-20 is an ABM system? In the parade it was placed between HQ-11 and HQ-22, not together with the ABM systems and from the wording in a China Daily article, quoting an retired PLA officer, it seems that it is more of a general-purpose SAM, not specialized for ABM.
