The situation is almost entirely focused on the south of Pangong Lake from the banks of finger 4's immediate southern counterpart to Reqin. India in the past always held the mountains right to the east of this southern region and they have considerably more build up and supply apparently. Focus where you are strong and attack where they are weak, using Tibetan "frontier forces". Rather clever textbook tactics but then that also means expected moves.
Since it's a predictable move to be honest so if the CCP and PLA were truly caught by surprise (assuming Indian ingress is true) then they are just simply too incompetent. Better to just back down if this is the case. More likely this is controlled and the expectation was always that the Indians will look for paths of least resistance. If this is expected and allowed to eventuate, then there may be escalation from PLA since this is the natural motivation for allowing such obvious gaps to exist and ingress to occur. Fireworks to be expected if so. If no fireworks, seems like CCP and PLA were just caught with their pants down.
Buddy, you need to calm down and not go worrying about the sky falling at every tiny issue.
Firstly the situation is very murky with a lot of Indian active fake news being spammed, so it would be falling for their BS to go making broad clams about the CCP and PLA based on their lies. Of course they are going to pain China in the worst possible light, it’s their main reason for existing apparently.
Secondly, even if we just assume for the sake of argument that the reports of India making some land grabs is correct, that doesn’t really mean anything, and is actually entirely to be expected if you think about it logically and rationally.
Its a very long boarder, with no fixed boarder posts or observation posts for the most part. Patrols are having to be done on foot and only a tiny fraction of the boarder can be monitored at any given time. You are acting like this is the Korean DMZ where every square metre is monitored 24/7 when that is absolutely not the case.
India has more troops forward deployed than China, so its pretty much a given that if they want to, they can infiltrate and occupy positions before PLA patrols can know about it. They could also actively use their local numerical superiority to their advantage by pressing at multiple points within the same PLA garrison zone knowing that initial contacts would tie down what limited manpower the PLA has in the zone to allow other groups to advance unopposed. That is about as basic a military strategy as there is to take advantage of superior numbers.
Unless China wants to match Indian boarder troop numbers, which China doesn’t want to do, then that is always a risk.
These peacetime land grabs are pretty meaningless to start with, as sitting on a feature is meaningless if the enemy can take it from you any time they want.
The key difference is that the PLA can take any India held position pretty much any time they want if the chips are down, but the Indians don’t have that option, which is why they are super precious about trying to occupy positions during peacetime, when their superior numbers count and the PLA’s war fighting dominance doesn’t come into play.
