evidence: Markey: The LAC runs slightly longer than the U.S.-Mexico border, including stretches of extraordinarily remote, mountainous terrain. Tawang is in the LAC’s "eastern sector," at the edge of the Indian state of Arunachal Pradesh. The main clashes of 2020 took place nearly 1,000 miles to the northwest in the Galwan Valley, while another important India-China standoff, at Doklam in 2017, played out in between the two at the "tri-junction" where western Bhutan meets India and China. [...] Of the various points along the LAC, Tawang holds unusual significance for both China and India. It is the site of an important Tibetan Buddhist monastery, believed to be where the sixth Dalai Lama was born in 1683. Beijing’s extreme sensitivities over Tibetan politics — including the question of the identity of the next Dalai Lama — play into their special attention to Tawang. [...] India rejects all such claims. New Delhi sees Arunachal Pradesh as integral to India’s territory and strategically vital for defending the rest of Northeast India. Whereas other remote, scarcely populated patches of territory along the LAC could shift between the effective military control of India and China without major consequence, Tawang is politically non-negotiable.
