evidence: On December 9, Chinese and Indian soldiers clashed at Yangtse, near Tawang, on the disputed China-India border. While much remains unclear about the clash, it seems that it followed an attempt by a body of Chinese soldiers to occupy tactically important terrain at the Yangtse Ridge, likely in order to cut the supply route of an Indian unit at an outpost nearby, oust it from its position, and alter the status quo in the area. [...] Importantly, the clash took place at a key location. Yangtse is a strategically important area long contested by China and India, where another clash took place in 2021. A Chinese border village connected with a road was recently constructed to establish a Chinese presence on the ground. The area is close to the highly sensitive city of Tawang, which China has long listed as a key demand in its territorial dispute with India and which has particular significance for the Dalai Lama’s reincarnation and, potentially, for the future of Tibet. [...] The Galwan clash, which followed years of mounting tensions in the China-India territorial dispute and particularly along the the Line of Actual Control (LAC), the long, disputed, and undemarcated de facto border between the two sides, provoked a deep crisis in relations between New Delhi and Beijing and a massive deployment of troops along the border. In spite of partial disengagement in some areas as a result of bilateral military talks and some limited diplomatic interaction in international forums, China-India relations have remained mostly frozen since 2020 because of the border.
