What is the specific situation in southern Tibet?

Southern Tibet is a disputed area, covering an area of about 90,000 square kilometers, and the actual control is in India. The north of the actual control line belongs to the Chinese side, with mountainous terrain and high altitude, and there is no traffic artery. South of the line of control belongs to the Indian side, and most of the land is mountainous, but it will soon reach the plain. From a purely high point of view, China seems to be giving orders.

But if there is friction and war between the two sides:

From a tactical point of view, the actual control of warp is beneficial to India, because it is convenient for the transportation guarantee of Indian logistics materials. However, India may assemble armored forces in one area, and it is difficult to conduct normal border patrol in the corresponding China area.

Strategically, an area in the actual line of control (Yadong) is beneficial to the general plan of China, because this area blocks the throat of southern Tibet and Indian mainland. If China blocks this throat and holds it, a large area of Indian territory on the east side of the Indian Corridor (including southern Tibet) will be controlled by China without strong support.

Judging from the regional political situation, because India has been operating in this area for many years, India has immigrated to this area in large numbers, and the surrounding small countries have all surrendered to India under military pressure, becoming a state of India (at present, the Sikkim Kingdom-the place where Tony Leung Chiu Wai and Carina Lau got married may be found on the map, but it has actually been incorporated into the territory of India), so the regional political situation is also unfavorable to China militarily.
