evidence: Why is Tawang in Arunachal Pradesh important to China? [...] During the India-China Special Representative dialogues on boundary resolution, State Councilor Wang Yi apparently wanted to discuss status of Tawang in Arunachal Pradesh as part of the dialogue. It is learnt that his Indian interlocutor, National Security Advisor Ajit Doval, told Councilor Wang that they would have to permanently wind up the dialogue as Tawang is non-negotiable for India. The 22nd round of SR dialogue was held on this day three years ago. [...] Tawang and Yangtze are key to Tibetan Buddhism, which the Communist Party of China (CPC) is trying to co-opt as part of Sinicization of Tibet. Tawang is the birthplace of sixth Dalai Lama Tsangyang Gyatso, who was reincarnation of the fifth Dalai Lama Ngawang Lobsang Gyatso or Great Fifth, the first Dalai Lama to become the spiritual and temporal head of Tibet.
