The India-China border has been witnessing tensions over the past month, with incidents reported in at least four different locations along the Line of Actual Control (LAC).
The border is not fully demarcated and the LAC is neither clarified nor confirmed by the two countries.
India-China border is divided into three sectors:
1) LAC in the western sector falls in the union territory of Ladakh and is 1597 km long.
2) The middle sector of 545 km length falls in Uttarakhand and Himachal Pradesh.
3) The 1346 km long eastern sector falls in the states of Sikkim and Arunachal Pradesh.
The main differences are in the Western and Eastern sectors. India sees China as occupying 38,000 sq km in Aksai Chin. In the east, China claims as much as 90,000 sq km, extending all across Arunachal Pradesh.
The middle sector is the least disputed sector, while the western sector witnesses the highest transgressions between the two sides
