Overview
The McMahon Line, drawn at the Simla Convention of 1914, is India's boundary with China in the eastern sector in Arunachal Pradesh. China disputes it, as it does Aksai Chin in the west.
It was drawn at the Simla Conference of 1913–14, where British, Tibetan and Chinese delegates met.
China does not accept it and claims much of Arunachal Pradesh.
The line largely follows the high Himalayan watershed, and Tawang lies south of it.
It runs about 890 km along the Himalaya.
India's official map shows it as the boundary with China in the east.
Its alignment was a key issue in the 1962 war.
China calls Arunachal 'South Tibet'.
