evidence: Last week, nearly 200 Chinese soldiers crossed into Indian territory in Tawang, the north-western district of Arunachal Pradesh, which shares a boundary with Bhutan to its west and Tibet in the north. [...] The incursion in Tawang last week was not the first time a large number of Chinese troops transgressed into Indian territory in this part of Arunachal Pradesh. China regularly makes incursion bids in the area. In 2016, for instance, about 250 Chinese troops had crossed into the Indian side in the district and had to be pushed back by the Indian Army. [...] For China, control over Tawang is linked to the legitimacy of its hold over Tibet. If the Dalai Lama finds a successor outside Tibet, the successor that the Chinese Communist Party may appoint (as it did in the case of the Panchen Lama) will not enjoy legitimacy and the spiritual authority required to exercise effective influence in Tibet.
