After Dalai Lama fled to India, Chinese security operation started in Tibet in 1971 and some Khampas started to settle down in the adjoining areas of the Himalayan border on the northern region of Nepal. They started to operate anti-China activities from Nepali territory, which was against foreign policy of Nepal. So Nepal launched military operations against Khampas. Many of them were killed, others fled and some surrendered. This episode is known as ‘Khampa Disarming Mission’ in Nepal’s military history.
