evidence: Kalapani is the area in the Darchula district of the Sudurpaschim province of Nepal that borders the eastern front of Uttarakhand in India. The area lies in the southern half of the Kalapani river basin or on the banks of the Mahakali river. It is situated at 3,650 m to 6,180 m above sea level and has an area of 35 square km. It only has some 100 people living in the area. Kalapani is a tri-junction point between India, Nepal and China. It is important to Nepal and India regarding the border dispute. But, not just that, India and China also find the area important as the pass to build a road connecting Indian pilgrims to Kailash Mansarover in Tibet. It is also a place of strategic importance for India and China to logistically build up military troops on the border. [...] Nepal’s claim - The 1816 Sugauli Treaty cost Nepal one-third of its territory but demarcated Kalapani and the disputed area as Nepal. Article 5 of the treaty states Nepal is east of the Mahakali (Kali) river with its source at Limpiyadhura. This is the beginning of the Kalapani dispute.
