The territory of which country do Altai Mountains NOT span through?

The Altai Mountains, also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia, and Kazakhstan come together, 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.

The region is inhabited by a sparse but ethnically diverse population, including Russians, Kazakhs, Altais, and Mongols. The local economy is based on bovine, sheep, and horse husbandry, agriculture, forestry, and mining. The controversial Altaic language family takes its name from this mountain range.
