The conquest of the Western Turks, known as the Western Tujue in Chinese sources, was a military campaign in 657 led by the Tang Dynasty general Su Dingfang against the Western Turkic Khaganate ruled by Ashina Helu.
Meanwhile, the general Su Dingfang had destroyed Goguryeo's ally Baekje in 660, left his assistant Liu Renyuan (劉仁願) in charge of the former Baekje capital Sabi, and then withdrew.
