Khüiten Peak, also known in China as Friendship Peak, is a mountain peak in the Altai Range. The international border between China and Mongolia runs across its summit point, which, at 4,356 metres (14,291 ft), is the highest point in the Altais and the highest in both Mongolia and Altay Prefecture in Western China. The peak is covered in snow year-round.

The Altai Mountains, also spelled Altay Mountains, are a mountain range in Central Asia and Eastern Asia, where Russia, China, Mongolia, and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E.
