When does the name Mongol first appear in Chinese records?

In the context of the history of Mongolia, the name Mongol first appears in a tribal list recorded during the Tang dynasty (618–907 CE) in China. Following this initial mention, the name disappears from the records and does not reappear until the 11th century, when the Khitan people—who established the Liao dynasty—ruled over parts of northern China and Mongolia.12
