Depsang Plain: The Controvercial LAC Between India And China, Why Is It Important?

Amid escalating tensions at the Line of Actual Control (LAC), the Depsang Plains—a 972-square-kilometer area at an altitude of over 16,400 feet—remains a flashpoint between India and China. Located within India’s Sub-Sector North (SSN), the Depsang Plains have seen heightened military activity, with both nations bolstering their presence in this strategically significant area.

Situated between the Siachen Glacier and the Chinese-controlled Aksai Chin region, the Depsang Plains hold immense military importance due to their flat terrain, which makes them ideal for the deployment of tanks. Over the years, this region has been the site of several standoffs between Indian and Chinese forces, notably in 2013 and 2015, as well as numerous smaller clashes when troops from both sides encounter each other during routine patrols.

Strategic Importance of the Depsang Plains

The geographical location of the Depsang Plains makes it a critical defensive zone for India in the broader context of Eastern Ladakh. Though much of the area’s significance lies in its military and strategic value, experts argue that it primarily functions as a defensive feature, helping to secure India’s northern frontier.

The ongoing friction in the Depsang Plains, however, predates the current LAC crisis. Reports suggest that Chinese forces have been obstructing Indian patrols well before the standoffs of recent years, preventing Indian troops from reaching patrol points (PP) 11, 12, 12A, and 13, all situated beyond a critical chokepoint known as the Bottleneck or Y Junction. Despite this, Indian forces continue to patrol up to the Bottleneck, preventing Chinese incursions beyond this point.

Historical Context of the Dispute

Tensions in the Depsang Plains go back several years, with two major standoffs in 2013 and 2015, where Chinese forces had crossed their claim lines but ultimately retreated. Despite these earlier incidents, the situation has escalated in recent months, though Indian officials maintain that no significant ground has been lost in 2024.

The dispute centers around differing interpretations of the LAC in the region. China’s claimed boundary lies just 1.5 kilometers from an Indian military camp near Burtse, an area that serves as a crucial base for Indian patrols. Indian patrols, however, must navigate on foot beyond the Bottleneck, taking either the northern route through Raki Nala to PP10 or the southeast route along Jiwan Nala towards PP13.

Current Concerns and Future Outlook

Despite the lack of a recent major confrontation, the situation in the Depsang Plains remains a cause for concern for Indian defense officials. The region’s vulnerability to Chinese incursions and its strategic importance ensure that it will remain a focal point in India-China relations, especially as tensions along the LAC show little sign of easing.

While both nations appear to avoid direct conflict in this region, the long-term security of the Depsang Plains will depend on continued vigilance and diplomatic efforts to resolve the broader LAC dispute.

Strategic Importance of the Depsang Plains

The Depsang Plains, located in Eastern Ladakh at an altitude of 16,400 feet, are a crucial and contested area between India and China. Situated near the Karakoram Pass to the north and Chinese-controlled Aksai Chin to the east, this flat terrain is strategically important for both countries. The area provides access to key routes, such as the Chip Chap river valley, which is seen as a potential military pathway from Aksai Chin into Ladakh.

Since the 1962 Sino-Indian war, China has maintained control over parts of the eastern Depsang, making it a flashpoint for ongoing tensions. The plains are ideal for military deployments, including tanks, making them a hotbed for frequent face-offs between Indian and Chinese troops.

India has been improving its infrastructure in the region, including a new route connecting the village of Murgo to Sasoma in Ladakh. However, the area remains vulnerable due to its proximity to Aksai Chin and China’s key G219 highway, which links Tibet and Xinjiang.

Depsang’s significance lies in its strategic location, and it will likely remain a focal point in the ongoing India-China border dispute as both sides strengthen their military presence in the region.
