Namka Chu or Kejielang River (Chinese: 克节朗河; pinyin: Kè jié láng hé)^[1] is a tributary of Nyamjang Chu that flows along the disputed border between India and China. The Indian side of the border is the Tawang district in Arunachal Pradesh. The Tibetan side of the border is in Tsona Dzong, Shannan province of Tibet. Namka Chu originates near the trijunction of Tibet, Bhutan and India and flows east for 26 km before joining Nyamjang Chu. It is about 200 kilometers away from the Misamari railhead and 60 kilometers from the Tawang road head. The Namka Chu valley was the scene of some of the most fierce fighting during the 1962 Sino-Indian war.
