Will India forcibly acquire southern Tibet and Aceh?

First of all, correct it. It's Aksai Chin area. Not Aceh.

Aksai Chin, in Turkic, means "White Stone Beach in China".

Both the new Tibet Highway and the planned new Tibet Railway pass through Aksai Chin area. The problem here is not very big. Mainly the Indians don't admit it, but the control is in our hands.

The main problem is southern Tibet, and the control is in India's hands, which is more troublesome.

Now India is not a question of whether it is necessary or not, but that India has already started practical actions. India has been emigrating to southern Tibet, and the recent announcement of sending 60,000 troops to southern Tibet is a direct manifestation of this action.
