Borders of Nepal

The Kalapani territory is an area under Indian administration as part of Pithoragarh district in the Kumaon Division of the Uttarakhand state, but it is also claimed by Nepal since 1997. According to Nepal's claim, it lies in Darchula district, Sudurpashchim Province. The territory represents part of the basin of the Kalapani river, one of the headwaters of the Kali River in the Himalayas at an altitude of 3600–5200 meters. The valley of Kalapani, with the Lipulekh Pass at the top, forms the Indian route to Kailash–Manasarovar, an ancient pilgrimage site. It is also the traditional trading route to Tibet for the Bhotiyas of Kumaon and the Tinkar valley of Nepal.

The China–Nepal border is the international boundary between the Tibet Autonomous Region of the People's Republic of China and Federal Democratic Republic of Nepal. It is 1,389 kilometres (863 mi) in length and runs in a northwest–southeast direction along the Himalayan mountain range, including Mount Everest, the world's highest mountain. The boundaries of this particular border have changed dramatically over time, especially when considering relatively recent events such as the Annexation of Tibet in 1949. However, some of the most significant developments of modern times would be the signing of the "Agreement on Maintaining Friendly Relations between the People’s Republic of China and the Kingdom of Nepal" in 1956 and the "Sino-Nepalese Treaty of Peace and Friendship" in 1960, both of which formally recognised Tibet as a part of China and confirmed the limits of the countries of China and Nepal as they are known today.
