Although it's only the fifth largest in the world, the Gobi Desert is the most expansive arid region on the Asian continent. The desert spans two countries, covering parts of northern and northwestern China and up into southern Mongolia. A rain shadow desert, Gobi suffers from having most of its rain blocked by the Himalyas. However, this doesn't mean the region receives zero precipitation. In fact, the Gobi gets about 7 inches of rainfall each year.
