The Sino-Indian War took place between China and India from October to November 1962, as a major flare-up of the Sino-Indian border dispute. There had been a series of violent border skirmishes between the two countries after the 1959 Tibetan uprising, when India granted asylum to the Dalai Lama. Chinese military action grew increasingly aggressive after India rejected proposed Chinese diplomatic settlements throughout 1960–1962, with China re-commencing previously-banned "forward patrols" in Ladakh after 30 April 1962. Amidst the Cuban Missile Crisis, China abandoned all attempts towards a peaceful resolution on 20 October 1962, invading disputed territory along the 3,225-kilometre (2,004 mi) border in Ladakh and across the McMahon Line in the northeastern frontier. Chinese troops pushed back Indian forces in both theatres, capturing all of their claimed territory in the western theatre and the Tawang Tract in the eastern theatre. The conflict ended when China unilaterally declared a ceasefire on 20 November 1962, and simultaneously announced its withdrawal to its claimed "Line of Actual Control".

The Sino-Indian border dispute is an ongoing territorial dispute over the sovereignty of two relatively large, and several smaller, separated pieces of territory between China and India. The first of the territories, Aksai Chin, is administered by China as part of the Xinjiang Uygur Autonomous Region and Tibet Autonomous Region and claimed by India as part of the union territory of Ladakh; it is mostly uninhabited high-altitude wasteland in the larger regions of Kashmir and Tibet and is crossed by the Xinjiang-Tibet Highway, but with some significant pasture lands at the margins. The other disputed territory is south of the McMahon Line, in the area formerly known as the North-East Frontier Agency and now called Arunachal Pradesh. The McMahon Line was part of the 1914 Simla Convention signed between British India and Tibet, without China's agreement. China disowns the agreement, stating that Tibet was never independent when it signed the Simla Convention.
Daulat Beg Oldi is a traditional campsite and current military base located in the midst of the Karakoram Range in northern Ladakh, India.
