In April 2013 India claimed, referencing their own perception of the Line of Actual Control (LAC) location, that Chinese troops had established a camp in the Daulat Beg Oldi sector, on their side of the Line of Actual Control. This figure was later revised to a claim. According to Indian media, the incursion included Chinese military helicopters entering Indian airspace to drop supplies to the troops. However, Chinese officials denied any trespassing having taken place. Soldiers from both countries briefly set up camps on the ill-defined frontier facing each other, but the tension was defused when both sides pulled back soldiers in early May. In September 2014, India and China had a standoff at the LAC, when Indian workers began constructing a canal in the border village of Demchok, Ladakh, and Chinese civilians protested with the army's support. It ended after about three weeks, when both sides agreed to withdraw troops. The Indian army claimed that the Chinese military had set up a camp inside territory claimed by India. According to scholar Harsh V. Pant, China gains territory with every incursion.
