China–Kyrgyzstan border

A high border along the Tien Shan from the Alay to the Kazakh tripoint, crossed by passes of 13,000 feet and more, where the Kirghiz herd their animals on both sides. Russia and China drew it in the 19th century; a railway from Kashgar through the Torugart Pass, begun in 2024, aims to link China to Europe while avoiding Russia.

The Tien Shan

After crossing the Alay Mountains the border follows the Tien Shan, the northernmost of the ranges radiating from the Pamirs, whose basins lie around 10,000 feet and whose main passes are at 13,000 to 14,000 feet. The Kirghiz, a mainly pastoral people, are the dominant group along it from the Tien Shan to about 80° E.[1]

The Treaty of Peking first made the line of Chinese pickets the boundary as far as the limits of the khanate of Kokand; the treaties of Tarbagatai (1864) and St Petersburg (1881), with their demarcation protocols, fixed the details after a Muslim revolt led by Yakub Beg weakened Qing control.[1]

The Torugart railway

On 27 December 2024 officials from China, Kyrgyzstan and Uzbekistan marked the start of work on a railway from Kashgar in Xinjiang across the Torugart Pass to Jalal-Abad and on to Andijan in Uzbekistan, about 486 km in all, most of it in Kyrgyzstan. Discussed since the 1990s, it gained momentum after Russia’s invasion of Ukraine in 2022; it is meant to shorten the route from China to Europe by 900 km while avoiding Russian territory. China holds 51 percent of the joint company building it.[2]
