China–Kazakhstan border
The China–Kazakhstan border (Kazakh: Қазақстан–Қытай мемлекеттiк шекарасы, romanized: Qazaqstan–Qytai memlekettık şekarasy; Chinese: 中哈边界; pinyin: Zhōnghā biānjiè; Dungan: Җунгуй–Хазахстан бянҗе), also known as the Sino-Kazakh border, is the international border between the People's Republic of China and the Republic of Kazakhstan.
The border line between the two countries has been largely inherited from the border existing between the Soviet Union and the PRC and, earlier, between the Russian Empire and the Qing Empire; however, it has been fully demarcated only in the late 20th and early 21st century. According to the international boundary commissions that have carried out the border demarcation, the border is 1,782.75 km (1,107.75 mi) long.
