I think corruption within the PLA has been mitigated by a significant extent, ever since the expulsion of Gu Junshan. You have to remember, endemic corruption was the problem standing in the way of the PLA 2016 reforms and the transitioning the PLA from a primarily ground force to one with much more naval and air power. Ever since the PLA anti-corruption drive started, things have moved along much much quicker, especially in terms of operations. The ability of the PLA to undergo the 2016 reforms (including the painful 300k troop cuts) and shifting of much assets towards the air force and navy shows you the corruption has drastically subsided. As for the Indian military, I'm not sure what levels of corruption they are suffering.
The issue I'm bringing up, is that we don't know. We have no idea exactly how successful Xi's anti-corruption campaign has been in getting the PLA to work. Besides the fact that the PLA has a deterrence force posture, we also have to note that the PLA has traditionally been where Chinese elites have parked their kids, usually in a non-combat role.
In any case, the Indians seem intent on a border force build-up, the Chinese seem intent on matching them, and while the Chinese have the politeness of not shouting random bullshit on public media channels, the Indians don't and seem incredibly hostile.
Here's to hoping that we can get a peaceful resolution of this madness.
