The Chinese Tang dynasty took control of the region of Jiaozhi (Giao Châu; roughly corresponding to the area of the modern Red River Delta) in 621 from the preceding Sui dynasty.

Effective control exercised by the Tang dynasty lasted until the 10th century, when Khúc Thừa Dụ took over as jiedushi in 905.
