The border between China and India.

The boundary between China and India is explained as follows:

The total length of China-India border is17km, which is mainly divided into three sections: west, middle and east, and Sikkim section.

The disputed territory in the western section is 33,000 square kilometers, including Aksai Qin area in Xinjiang and Karakorum Corridor. The outside world calls it Central Kashmir, which is connected with Kashmir controlled by India and Kashmir controlled by Pakistan. This disputed area, except barrigas (45 square kilometers) occupied by Indian, is actually controlled by China, and is under the jurisdiction of Hotan in Xinjiang and Ali in Tibet. How far is this place from the Indian capital New Delhi? 3 kilometers! Moreover, the new Tibet highway runs through this area, providing a steady stream of logistics supplies for the garrison in this area, so the strategic value of this area is immeasurable! Once India makes any changes to China, it can push Delhi in this direction.

In the middle section, China, Tibet, and Ali region are bordered by Indian states of Himachal Pradesh and Uttar Pradesh. As can be seen from the map, the disputed area can be roughly divided into four parts. Juwa and Qurang are an area of 332 square kilometers; Shibuqi mountain pass covers an area of 35 square kilometers; Mulberry, Allium fistulosum and Bolin are one area, with an area of about 145 1 km2; Uige, Lanchong and Labdi cover an area of 855 square kilometers. The total area of the four blocks exceeds 2 square kilometers, and they are all actually controlled by India. This area is located in the Himalayas. You can imagine how bad the natural environment here is. If you want to station troops or fight in this area, it is really difficult to solve the logistics supply.

The eastern region, commonly known as southern Tibet, has 90,000 square kilometers of disputed areas, all of which are actually controlled by India. The historical reason for the controversy is that at the Simla meeting in 19 14, the local governments of Britain and Tibet agreed to draw the McMahon line and incorporate the area south of the Himalayas into the territory of India. This area is vast and rich in aquatic plants, but there is no land transportation line with the inland of China, so it is difficult to supply. But the Tawang area is an exception, because there is a natural barrier at the Xishan Pass, and there is no logistics supply problem. At the same time, Tawang is the hometown of Cangyang Gyatso, the sixth Dalai Lama, and a holy place in the hearts of Tibetans. Tawang is of great significance to China. Although it was occupied by Indians, it must be recaptured when the time is right.

China and India are in the border area of Sikkim. Recently, the media widely reported that our road construction in Donglang area was blocked by Indian troops crossing the line, and this incident happened in this area. From the map, the Donglang area is located at the southernmost tip of Yadong County in Tibet, mainly referring to the Donglang River Basin, with an area of about 1 square kilometer. India calls this bulge Dolan Highland, which borders India in the west, Bhutan in the east and siliguri-Chadwa Corridor in India. The Siliguri Corridor is a key point connecting East and West India, and its narrowest point is only about 20 kilometers. India has been worried that the siliguri-Chadwa Corridor will be cut off, and the links between the northeastern Indian states and India will be cut off. No matter how unreasonable the Indian side is, China will continue to improve the infrastructure projects in this region. Besides, the Yarlung Zangbo River, which flows through southern Tibet and the upper reaches of the Yarlung Zangbo River in northeastern India, is located in Tibet, China, so the water source in this area is controlled by Beijing.
