This article explores the intricate geopolitical dynamics of the India–China border, with a particular emphasis on Demchok village in Ladakh’s Leh district—a strategically significant settlement situated along the Line of Actual Control (LAC). Historically inhabited by nomadic communities, Demchok has functioned as an informal intelligence asset for India, owing to the residents’ intimate knowledge of the local terrain. The area’s contested status is exacerbated by conflicting cartographic depictions and divergent interpretations of geographical features such as the Lahri Stream and Peak, reflecting the enduring tensions between India and China. Drawing upon historical records, travelogues and official reports, this study traces the evolution of the India–China frontier and highlights Demchok’s historical relevance. Using a Geographic Information System (GIS) mapping, the research visualises overlapping territorial claims and the current positioning of the Chinese People’s Liberation Army (PLA).
