Do either China or India actually care about what happens around Aksai Chin? Nobody lives there and no country is stupid enough to attack over the Himalayas anyway. I always got the vibe that it's a dick-measuring staring contest that started because the British fucked up their pull out of the region.

It's not like China actually expects Arunachal Pradesh given that they have basically no ability to project power over the Himalayas and it's not like India actually expects Aksai Chin given that they also have basically no ability to project power over the Himalayas.
