The association of Khitai with China meant that the most enduring trace of the Khitans' power is names that are derived from it, such as Cathay, the medieval Latin appellation for China. Names derived from Khitai are still in use, such as the Russian, Bulgarian, Uzbek and Mongolian names for China. However, the use of "Khitai" to mean "China" or "Chinese" by Turkic speakers within China, such as the Uyghurs, is considered pejorative by the Chinese authorities, who have tried to ban it.
