evidence: But the matter didn’t end there. A note was appended to the Simla accord, which contained a map showing a part of Tibetan territory as Indian, based on a thick red line known as the McMahon line. Furthermore, China was barred from any rights and privileges of the Accord with respect to Tibet. [...] 2) The Eastern Sector – The Indian state of Arunachal Pradesh, which China calls South Tibet, covering an area of 83,743 sq.km (32,333 sq.mi) – currently occupied by India. [...] India had enjoyed certain privileges with regard to Tibet under the Simla Agreement, including those regarding trade and commerce. If the Simla accord is legal, then it serves India’s cause; and if it is illegal, China’s. However, when China annexed Tibet in 1951, India under Nehru recognized it as Chinese territory, thus giving up those privileges and undermining Tibet’s sovereignty (which it may have momentarily enjoyed during the time of the Simla agreement). Thus in a sense the Indian government tacitly admitted that the Simla agreement was effectively illegal, which to this day remains China’s official position. In doing so, India weakened its own position with respect to the border dispute.
