Right. And that is the problem spot. Disengagement there started in July but obviously was not completed. China probably wants India to go back behind pp15, but India is refusing. My guess is because India wants China to remove the new post on its side of the dotted line. Since both sides have not come to an agreement, the standoff continues in that yellow circle. In other areas, it has effectively been resolved.
Meanwhile, the only Chinese position in the gogra sector is the camp nearly 6 km from the LAC(Indian claim line). Anyone who believes otherwise is welcome to provide clear evidence supporting their arguement).
Yes this is what I personally suspect as well. China wants India totally out of the dotted pink to blue line areas encircled/ no man's land/ 20% remaining of total dispute.
India wants to take it since China's already won the 80% of total dispute. I think this is more than understandable for India. But China is exerting its strength here and not playing nice with India BECAUSE India went back on (understandably but still dirty move) past 1990s agreements and Wuhan consensus on not antagonising each other and not upping miltiary patrols and confrontations. India has and China interpreted this as needing punishment. Hence China is refusing to budge even though it's already gotten 80% of the total dispute.
If India is willing to convert the northern sides to Gogra HS of this remaining dispute into a buffer just like it agreed to at Pangong side, I'm sure China would disengage. But this would mean India got absolutely zero from even the most India favoured interpretations of historical changes to control lines (not LAC, I mean the blue line of where China controlled in actuality) and claim lines.
China's claim lines were far east in 1950s and then 1960 moved up much more after India rejects 1959 offer. After 1960's China and India fought the war and the post 1960s claim line of China's is basically that one your maps show and my maps show as the pink dotted line.
This is already been moved west and then west and then west and the control line (blue) has moved west and west and west.
