The Kazakh autonomous prefecture of Ili (伊犁哈萨克自治州) is a special case of administrative divisions in China, its legal status is actually an administrative division at prefecture-level. It is the only autonomous prefecture in the country that has both directly administered county-level divisions and prefectures under its jurisdiction. When the People's Republic of China was established in 1949, the 3 prefectures of Altay, Ili and Tacheng were directly under the leadership of Xinjiang provincial government. The Mongol autonomous prefecture of Bortala was founded from Bole, Jinghe and Wenquan, 3 counties of Ili Prefecture (伊犁专区) in July 1954. The Kazakh autonomous prefecture of Ili had 3 prefectures of Altay, Ili and Tacheng under its administration when it was established in November 1954. The Ili Prefecture (伊犁专区) firstly ceased to be as a separate prefecture in December 1955, its county-level administrative units were directly administered by the autonomous prefecture of Ili. Since then, the Kazakh autonomous prefecture of Ili has existed as a separate administrative division. Its administrative divisions have either been reduced to the geographical scope of the former Ili Prefecture or expanded back to the territory of the former 3 prefectures. As a separate administrative unit, Ili Prefecture (伊犁地区) existed until its final dissolution in 2001. From Wikipedia
