A border skirmish between India and China in the Himalayan region, which China claimed had been wrongly given to India by the McMahon Line decision in 1914. Chinese forces began an offensive across the McMahon Line into India. Indian forces retreated and Assam appeared to be at the mercy of China, when the latter announced a ceasefire and withdrew to the Tibetan side of the Line, while retaining parts of Ladakh in Kashmir. Some of the border areas are still disputed.
