Since deadly clashes between India and China on their 2,100-mile disputed border — known as the Line of Actual Control (LAC) — nearly four years ago, the two countries have remained in a standoff and amassed an increasing number of troops on either side of the LAC. While India and China have held regular exchanges at the corps commander level since 2020, each side has also continued to militarize and invest in infrastructure in the high-altitude border regions, which may exacerbate risks of clashes or escalation. India-China competition has also deepened beyond the land border, particularly in the Indian Ocean region.
