The US-based NGO found more than 800,000 Tibetan children between the ages of six and 18 “are now housed in these state-run institutions", the news portal reported.

“The colonial boarding school system in Tibet is a core element of the Chinese Communist Party’s systematic effort to co-opt, undermine, and ultimately eliminate Tibetan identity in an attempt to neutralize Tibetan resistance to Chinese rule,” the group said in a report published Tuesday.

Tibet is a region covering much of the Tibetan Plateau in Tibet Autonomous Region, China. It is the traditional homeland of the Tibetan people as well as some other ethnic groups such as Monpa, Tamang, Qiang, Sherpa, and Lhoba peoples and is now also inhabited by considerable numbers of Han Chinese and Hui people.

China took control over Tibet in 1950.

The 1959 Tibetan uprising or the 1959 Tibetan rebellion began on 10 March 1959, when a revolt erupted in Lhasa, the capital of the Tibet Autonomous Region, which had been under the effective control of the People's Republic of China since the Seventeen Point Agreement was reached in 1951.

Armed conflict between Tibetan guerillas and the People's Liberation Army(PLA) had started in 1956 in the Kham and Amdo regions, which had been subjected to socialist reform. The guerrilla warfare later spread to other areas of Tibet and lasted through 1962. The anniversary of the uprising is observed by Tibetan exiles as the ''Tibetan Uprising Day''.

In early 1959 during the Tibetan uprising,their spiritual leader (Nobel Peace Winner) the Dalai Lama and his retinue fled Tibet with the help of the CIA's Special Activities Division, crossing into India on 30 March 1959. He has been based in Dharamshala in Himachal Pradesh since then.
