The Battle of Dulu was a battle between the Tang and Nanzhao forces against the Tibetan Empire and Abbasid Slaves Soldiers that took place near Kunming in the spring of the 17th year of Zhenyuan Period of the Tang dynasty.

Wei Gao, the governor of Jiannan and Xichuan, and Yi Mouxun, the king of Nanzhao, jointly attacked the Empire of Tibet. The Arabs sent Slave Soldiers to Tibet. One night, the Tang Dynasty coalition forces crossed the Lu River and destroyed the enemy's main force. After the battle, the Book of Tang says that:

"the Kang, the Abassids Arabs and other soldiers and the Tibet chieftains all surrendered, and 20,000 heads of armor were captured"

This battle was a major event in the introduction of Islam into China through military means.^[6]
