Battle of Talas
Turks had to wait two and a half centuries before reconquering Transoxiana, when the Karakhanids reconquered the city of Bukhara in 999. Denis Sinor said that it was interference in the internal affairs of the Western Turkic Khaganate which ended Chinese supremacy in Central Asia, since the destruction of the Western Khaganate rid the Muslims of their greatest opponent, and it was not the Battle of Talas which ended the Chinese presence.
