China–Kyrgyzstan border

The China–Kyrgyzstan border is 1,063 km (661 mi) in length and runs from the tripoint with Kazakhstan following a roughly south-west line across various mountain ridges and peaks of the Tian Shan range down to the tripoint with Tajikistan. The border divides (from north to south/east to west) Issyk-Kul Region, Naryn Region and Osh Region in Kyrgyzstan from Aksu Prefecture (to the north and east) and Kizilsu Kyrgyz Autonomous Prefecture (to the south and west) in Xinjiang Uygur Autonomous Region, China.
