Russian tank technology (Armata is probably the best tank in the world right now, shame that Russia can't afford a T-90-scale fleet of them) is best in the world, true, and the Chinese have made major design mistakes with the ZTZ-99A, using Western turret design without understanding it (relatively poor side armor), but the fact of the matter is, India isn't running Armatas, it's running T-90s.
And Chinese tank design isn't that bad.

Also, I'll point this out for the ZTQ-15. There's a claim going on that with modern ERA, the ZTQ-15 is expected to defeat Mango type penetrators. So, ironically, while the ZTQ-15 is pretty toast against an Abrams head-on, it's good enough to survive against an Indian or Vietnamese T-90S long enough for its ATGM to hit the target.
If you recall, the ZTZ-98 family was designed to counter Abrams tanks, even if 1:1 they might not be completely comparable (note the Abrams is currently heavy as all hell). The ZTZ-96 family, on the other hand, was designed to counter Soviet T-72s. The ZTQ-15 can possibly now be considered the successor to the ZTZ-96; it gives up firepower compared to the ZTZ-96, but it has extremely good weight and mobility characteristics and likely comparable armor due to the current generation ERA.
