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 in November 1726, he picked up
Lorenz Lange and Ivan Bucholz and sent out cartographers to survey the border. The negotiators on the Manchu side were
Tulishen and
Dominique Parrenin. After six months a draft treaty was worked up, but it became clear that neither side had adequate maps. In May Vladslavich and Tulishen went back to
Selenginsk near Lake Baikal to get the waiting maps. By 31 August a draft treaty was drawn up ('Treaty of Bura' after a nearby river). Work quickly began setting up border markers starting from
Kyakhta on the
Selenga River. The 'Abagaitu Letter' listed 63 markers from Kyakhta east to the
Argun River. The 'Selenginsk Letter' listed 24 markers west from Kyakhta to the "Shabindobaga River on the northwest slopes of the
Altay Mountains". The 'Treaty of Bura' was sent to Peking to be combined with work already done there. The result was sent back to the frontier and the
Treaty of Kyakhta was signed on 25 June 1728. The treaty had three official versions, in Russian, in Latin and in Manchu. No official Chinese version of the treaty exists. ==Articles==
