China contains Mount Everest on its northern side. The mountain lies on the China–Nepal border in the Himalayas, with its summit marking the international boundary rather than belonging entirely to one country.
China’s side of Everest is in the Tibet Autonomous Region. Nepal’s side is in Koshi Province, and the two countries use different names: Mount Everest in English, Sagarmatha in Nepal, and Qomolangma in Tibetan.
The standard route from China approaches the summit through the North Col, while the famous southern route begins in Nepal. Both routes lead to the same summit elevation, which was officially measured as 8,848.86 metres in 2020.
A common mistake is to answer Nepal because most climbing expeditions use the southern approach. Nepal shares the summit, but China contains Everest’s northern face and base-camp region.
