Vast desert area of southern Mongolia and northern China (4)

I believe the answer is:

gobi

(Other definitions for gobi that I've seen before include "Area of sand" , "Large desert plateau of southern Mongolia and northern China" , "The . . . . Desert is a barren plateau of S Mongolia and N China" , "Large, mainly Mongolian, desert" , "Large Far Eastern desert" .)

I've seen this clue in The Guardian.
