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.[citation needed]
History
The origins of the border date from the mid-19th century, when the Russian Empireexpanded into Central Asia and was able to establish its control over the Lake Zaysan region. The establishment of the border between the Russian Empire and the Qing Empire, not too different from today's Sino-Kazakh/Kyrgyz/Tajik border was provided for in the Convention of Peking of 1860;[1][2] the actual border line pursuant to the convention was drawn by the Treaty of Tarbagatai (1864) and the Treaty of Uliassuhai (1870), leaving Lake Zaysan on the Russian side.[3][4][2] The Qing Empire's military presence in the Irtysh basin crumbled during the Dungan revolt (1862–77). After the fall of the rebellion and the reconquest of Xinjiang by Zuo Zongtang, the border between the Russian and the Qing empires in the Ili River basin was further slightly readjusted, in Russia's favour, by the Treaty of Saint Petersburg (1881) and a series of later protocols.[2] In 1915 an agreement was signed more precisely delimiting the border the Ili Valley and Dzungarian Alatau region.[2]
The southernmost section of the frontier (i.e. roughly the southern half of the modern China–Tajikistan border) remained undemarcated, owing partly to the ongoing rivalry between Britain and Russia for dominance in Central Asia known as the Great Game; eventually the two agreed that Afghanistan would remain an independent buffer state between them, with Afghanistan's Wakhan Corridor being created in 1895.[2] China was not a party to these agreement and hence the southernmost section of the China-Russia boundary remained undefined.[2]
After Kazakhstan became an independent country, it negotiated a border treaty with China, which was signed in Almaty on April 26, 1994, and ratified by Kazakh President Nursultan Nazarbayev on June 15, 1995. According to the treaty, a narrow strip of hilly terrain east of Lake Zhalanashkol which the USSR and China had contested in 1969 has become recognized as part of China.[6]
To delineate certain small sections of the border more precisely, additional agreements were signed on 24 September 1997 and 4 July 1998.[7][8] Over the next several years, the border was demarcated on the ground by joint commissions. According to the commissions' protocols and maps, the two countries' border line is 1782.75 km long, including 1215.86 km of land border and 566.89 km of border line run along (or across) rivers or lakes. The commissions' work was documented by several joint protocols, finalized with the Protocol signed in Beijing on May 10, 2002.[7][8] The agreements are not recognized by the government of the Republic of China on Taiwan.[citation needed]
In 2011 a cross-border free trade area opened on the border at Khorgos in an effort to boost Chinese-Kazakh trade.[9]
