South Tibet

South Tibet is a literal translation of the Chinese term Zàngnán (藏南), which may refer to different geographic areas:

• The southern part of Tibet, covering the middle reaches of the Yarlung Tsangpo valley between Saga to the west and Mainling to the east, as well as neighbouring areas located betweent the Himalayan range to the south and the Transhimalayan range to the north. The region extends around 1,000 km from west to east and 300 km from north to south. By this definition, South Tibet is including most of modern-day Prefectures of Shigatse, Lhasa, Lhoka (Shannan) and Nyingchi (Nyangtri).
• South Tibet may also refer to a shorter section of the Yarlung Tsangpo and tributaries, covering most of Lhoka (Shannan) and Nyingchi (Nyangtri) Prefectures from the confluence with the Kyi Chu to the west up to the beginning of the Yarlung Tsangpo Grand Canyon near Mainling to the east.
• When used in relation to the Sino-Indian border dispute, South Tibet is a term mainly used by the People's Republic of China to refer to the territories located south of the McMahon Line, established through the Simla Accord (1914), administered by the Republic of India as part of the state of Arunachal Pradesh and claimed by both the Republic of China and the People's Republic of China.
• By extension, South Tibet may also refer to the entire state of Arunachal Pradesh^{[citation needed]}, although the disputed areas do not cover its entire territory.
