China–Nepal border

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.
