CCP's intentions and way of working now has not only become 90% clear but it also makes absolutely perfect sense. Every. Single. Move.
India wants remaining 20% and building up to it and doing more patrols. India aggressively attacking China with propaganda and going against past agreements for mutual respect and neutrality at least. India scraps 370 and acts like it's a supa powa when it is super beggar. Indian arrogance is very much unchecked and increased patrol confrontations leading to fights ever since 2011.
China thinks we gotta respond. We need to achieve following main objectives:
1. Further secure Aksai Chin from the increasingly aggressive and arrogant, self assured Indians who may do something silly if their arrogance is left unchecked ... raping Kashmiris and murdering civilians is easy but a normal man does not derive pleasure or arrogance from that. Only SOME Australian special forces murdering Afghani children (but apparently also very systemic in their racism and killing of civilians for fun) and Japanese soldiers of WW2 get a manhood boost from such depravity.
2. Send India and its political elite a message that China is the rock, India is the egg thinking it's Uranium. Let them know that the actions described above are going to be responded to. This would prevent Indians from growing unfounded ideas of being supa dupa and acting as if it has the strength. Since India doesn't want to play diplomacy (1990s to 2015 talks and agreements on good relations), and India wants to act with military like it does in Kashmir, then China will engage with military means as well.
3. Ensure 20% stretch is at least vacated of Indians. This is still not achieved and negotiations surely have China demanding India vacate this stretch of land like they did in Pangong and in return, PLA will disengage wherever it has position west of blue line. This is to become a buffer zone if it cannot become properly demarcated in a way that China feels comfortable - so surely west of blue line but probably a little east of pink dotted.
4. Force India to either demarcate line between pink dotted and blue or make this entire 20% stretch a buffer.
5. These when achieved will totally secure Aksai Chin in a way it simply isn't. If line is demarcated, Indian can not claim Aksai Chin anymore. If it is a buffer, India cannot enter buffer and pose military threats towards Aksai Chin. This also prevents fighting from occurring as Indian patrols will have to be met and "engaged" i.e. hugged and pushed out if they don't leave willingly.
This is why there are Indian and possibly Chinese positions in the 20% still. As Pangong side is a buffer, both sides are talking right? What are they talking about? PLA must have forward positions still because if they didn't why would the US and Indian governments both say that there are ongoing matters to be worked out and with the US clearly saying China is "inside India". And by that they mean the 20% is Indian. It isn't. This is where different parties have different semantics BUT it is fucking easy and clear to understand.
Don't get caught up with US saying that land is Indian. Of course they'll say that. Indians like Shukla and Rahul Gandhi also consider that as India and then much more as well. This 20% is disputed and PLA in inside it to either continue the stand off or until talks result in Indians agreeing to making it a buffer just like on Pangong or to demarcate the line.
Easy as piss to understand.
