Nepal and China are the closest countries to Mount Everest.
Mount Everest sits on the border between Nepal and the Tibet Autonomous Region of China, which is a part of China. Therefore, both countries share the mountain and are equally "closest".
Several sources confirm this location:
- National Geographic: "Mount Everest is a peak in the Himalaya mountain range. It is located between Nepal and Tibet, an autonomous region of China."
- Britannica: "Mount Everest is on the crest of the Great Himalayas of southern Asia. It lies on the border between Nepal and the Tibet Autonomous Region of China."
- USA Today: "Mount Everest is located between Tibet, an autonomous region of China, and Nepal."
While other Himalayan countries are geographically close to the range containing Everest, only Nepal and China directly border the mountain itself.
