Line of Actual Control
The Line of Actual Control (LAC) is the effective border between India and China. The LAC is 4,057-km long and traverses three areas of northern Indian states: western (Ladakh, Kashmir), middle (Uttarakhand, Himachal Pradesh) and eastern (Sikkim, Arunachal Pradesh). Quote: "India is used to incursions by Chinese troops across the 4,057-km LAC in all the three sectors—western (Ladakh), middle (Uttarakhand, Himachal Pradesh) and eastern (Sikkim, Arunachal Pradesh)— in a bid to strengthen China's claim over disputed areas and ensure New Delhi does not change its Tibet policy."
