evidence: The longest disputed border in the world, the India-China boundary has experienced recurring conflicts since 1962. Incursions tend to occur in two distinct regions: Aksai Chin, a region north of Nepal that is controlled by China but claimed by India, and Arunachal Pradesh, a region east of Bhutan that is controlled by India but claimed by China. [...] Although hotspots occur throughout Aksai Chin and Arunachal Pradesh, the researchers’ game-theory analysis indicates that only the incursions in Aksai Chin are part of a coordinated effort. Building on insights from game theory, the researchers predict that China is trying to establish permanent control over Aksai Chin by allocating more troops for a longer period of time than India. [...] "Knowing there are more incursions in the western sector is not a surprise," he said. "Aksai Chin is a strategic area that China wants to develop, so it’s very critical to them. It’s a vital passageway between China and the Chinese autonomous regions of Tibet and Xinjiang."
