Indian Prime Minister Narendra Modi is “not in a good mood,” U.S. President Donald Trump recently declared, as he offered to mediate India’s resurgent border conflict with China. After years of bending over backward to appease China, Modi has received yet another Chinese encroachment on Indian territory. Will this be enough to persuade him to change his approach?

While India was preoccupied with the COVID-19 crisis, China was apparently planning its next attempt to change the region’s territorial status quo by force. Last month’s swift and well-coordinated incursions by People’s Liberation Army troops into the icy borderlands of India’s Ladakh region were likely the product of months of preparation. The PLA has now established heavily fortified camps in the areas it infiltrated, in addition to deploying weapons on its side of the Line of Actual Control (LAC), within striking distance of Indian deployments.

China’s “unexpected” maneuver should not have been unexpected at all. Last August, China’s government vigorously condemned India’s establishment of Ladakh — including the Chinese-held Aksai Chin Plateau — as a new federal territory. (China seized Aksai Chin in the 1950s, after gobbling up Tibet, which had previously served as a buffer with India.) And the PLA had been conducting regular combat exercises near the Indian border this year.
