evidence: Since 1996, China has offered an exchange of territory with Bhutan, seeking to relinquish its claim to disputed regions in the north in exchange for Bhutan ceding more strategically important territory in the west. For Beijing, Doklam remains the goal: It sits at a junction that connects Tibet, Bhutan, and India, and it would provide the Chinese People’s Liberation Army with a tactical advantage. To make this a more attractive proposition, China noted that the territory in the north was far larger than the territory it sought. Although the initial offer nearly worked, the 1996 talks ultimately broke down. [...] Similarly, the Chumbi Valley to the north of Doklam—often described as a Chinese dagger into Indian territory—represents a weakness for China, which sees the ancient gateway to Tibet as vulnerable to a pincer movement, in which Indian troops could strike from both sides of the valley at once—from Bhutan and India. By extending its claim by 89 square kilometers south of the intersection with Bhutan and India, China hopes to gain a vantage point that could serve both offensive and defensive purposes in a potential conflict with India.
