what's the point of this ??
This area is known trouble spot where China can more easily make a demonstration...the topography suits them mightily if you look at where their terrain features are compared to India...(the name nanda devi on the map should say a lot).
India has lot more mountains and ravines on its side that break up logistic network lot more to get to the final border zones in this area....compared to China which has relatively flat tibetan plateau on its side.
That drives the costs more for one side to meet in equal way. So the other side knows it and what is low hanging fruit if it wants to prod easily.
In fact this was one of the likeliest candidates where PLA could have made an armed venture of note if it elected to during the 2020 standoff....and it would have been hard for India to meet it in this spot.
In other areas India holds the advantage (if it wants to prod in similar way)....and others are more 50/50.
It depends on the end in topography and what the motivations are to test the other side.
