Chinese consider themselves as a world military power but unfortunately PLAN cant even effectively fight beyond 500 km from China lol. Speaking of Barak 8,seems you have a special feelings for it because despite randomradio and others explaining it's capabilities in retail you still are in denial. MRSAM version of Barak 8 can reach Mach 3 and has successfully showed its capability in the recent conflict. It is safe to say Barak 8 performed far better than Hoe Qock 9B which failed to defend even strategic targets inside Pakistan lol.
You also forget about the AD1 and PDV 1 systems which India has already deployed around the capital. PDV can easily intercept any ballistic missile in Pakistans arsenal. Infact considering that China cannot even build a system which can perform as good as Barak 8 it's quite likely HQ19 is inferior compared to PDV 1 even let alone PDV 2 and cannot intercept complex maneuvering targets such as Pralays let alone hypersonic glide vehicles such as LRHASM or BM04. That's considering if your Hoe Qock 19 will survive the initial days without getting hit by Rudram ARMs lol. After all, the strategic depth of your attack dog in South Asia is poor and they cannot station HQ19 too far from the border.
BTW, THAAD is not designed to intercept cruise missiles, and you said HQ19 is the same as THAAD. You and many other comrades are also boasting HQ19 can defeat Brahmos. I hope you guys are not so illiterate that you cannot distinguish between terminal targets travelling in ballistic trajectory and cruise missiles flying at low altitudes lol.
You import S400 because your Politbuero members don't even truth their own scientists and systems. After all the General Secretary had to run to Russia to beg for supersonic cruise missile technology 20 years ago, it was only after Russians told you nyet you made YJ12, which uses roughly the same design as the STAR missile which we are going to use for target practice
I also remember someone who was boasting how their country can intercept Mach 25 ICBM with decoys and MIRV but their air defence systems failed even against 10-15 cruise missiles



. Truly if you are the average quality of academician that China churns out, then the great mathematician Shing Tung Yau was correct in his assessment that China is no match compared to the US in university level education even now.
