• The row between India and China on the visit of the Dalai Lama to Arunachal Pradesh spiralled.

Points to remember:

• Arunachal Pradesh is at the heart of the Sino-Indian boundary dispute in the eastern sector.
• McMahon Line, frontier between Tibet and Assam in British India, negotiated between Tibet and Great Britain at the end of the Shimla Conference (October 1913–July 1914) and named for the chief British negotiator, Sir Henry McMahon.
• It runs from the eastern border of Bhutan along the crest of the Himalayas until it reaches the great bend in the Brahmaputra River where that river emerges from its Tibetan course into the Assam Valley.
• The dispute in this zone is over territory south of the McMahon Line in Arunachal Pradesh, which includes Tawang — which is on the Dalai Lama’s itinerary.
• The McMahon Line was the result of the 1914 Simla Convention, between British India and Tibet, and was rejected by China.
