The Treaty of Kyakhta (or Kiakhta), along with the Treaty of Nerchinsk (1689), regulated the relations between Imperial Russia and the Qing Empire of China until the mid-19th century. It was signed by Tulišen and Count Sava Lukich Raguzinskii-Vladislavich at the border city of Kyakhta on 23 August 1727. Results Diplomatic and trade relations were established that lasted until the mid-19 century. It established the northern border of Mongolia (what was then part of the Qing-Russian border). The caravan trade from Kyakhta opened up (Russian furs for Chinese tea). Agreement with Russia helped China expand westward and annex Xinjiang. Qing subjects are referred to as those from "Dulimbai gurun" in Manchu in the Treaty. Background By the 1640s Russian adventurers had taken control of the forested area north of Mongolia and Manchuria. From 1644, the rule of the Qing dynasty established its capital in Beijing and took control of the Central Plains region.

The Manchus wanted an agreement because they were worried about possible Russian support for the Oirats and did not want disobedient subjects fleeing to the Russians. Many of the Cossacks in Siberia were rather close to bandits and could cause trouble if not restrained by the Tsar. The Russians had neither a reason nor the means to push south and were more interested in profitable trade. The Russians had no hope of sending a serious army this far east and the Manchus had no interest in the frozen forests of Siberia. Negotiations From the 1710s the Kangxi Emperor began to put pressure on Saint Petersburg for an agreement, largely by interfering with the caravan trade. The Lev Izmailov mission in 1719/22 to Peking produced no results. Just before his death, Peter the Great decided to deal with the border problem. On 23 October 1725 Sava Vladislavich, a Serb in the Russian service, left Saint Petersburg with 1,500 soldiers and 120 staff including map-makers and priests. Before reaching Peking
