Kalapani is a strategically important valley currently administered by India. It forms a part of the Pithoragarh district in the state of Uttarakhand.
Its location is crucial as it lies along the significant Kailash Mansarovar route, a pilgrimage path for many.

A key geographical feature defining the border in this area is the Kali River (also known as the Mahakali River). This river historically demarcates a significant portion of the boundary between India and Nepal.
The foundation of the current border dispute lies in the Treaty of Sugauli. This treaty was signed in 1816 between the Kingdom of Nepal and British India, following the conclusion of the Anglo-Nepalese War.
Key Provision: The Treaty of Sugauli officially designated the Kali River as the western boundary of Nepal.
Territorial Division:
The fundamental issue leading to the ongoing boundary dispute is a discrepancy in locating the actual source of the Kali River.
Both India and Nepal have produced their own maps, each supporting their respective claims regarding the river's origin and, consequently, the alignment of the international border in the Kalapani region.
