On this day, 336 years ago, on August 22, 1689 (July 8, 1689, the lunar calendar), China and Russia agreed on the border treaty "Treaty of Nibchu." The first formal treaty: The Treaty of Nibchu between China and Russia in 1689. The Treaty of Nibchu was the first border treaty signed between the Qing Empire and Russia. It was also the first formal treaty signed between China and other countries. After a military conflict between the two countries in the Jaksa region, on August 22, 1689, the Russian plenipotentiary, Army General Fyodoro, and the Qing Dynasty plenipotentiary led the Minister of Guards, Soetu, in Nebuchu. The boundary treaty signed by (now Nerchinsk, Russia) is as follows: from the Gorbiti River, a tributary of the Heilongjiang River, to the Outer Xing 'an Mountains, to the sea, Lingnan belongs to China, and the north of the ridge belongs to Russia; the west is bounded by the Erguna River, and the west belongs to China, and the east belongs to Russia; Jaksa belongs to China, and the city of Jaksa is demolished, and the Russians are moved back to the Russian territory; hunters from the two countries are not allowed to cross the border without authorization, otherwise they will be arrested and punished. More than 15 people collectively cross the border to rectify the law; Border trade is allowed if people of the two countries carry documents (passports); the two countries are not allowed to take in fugitives. The treaty is available in Chinese, Russian, and Latin, with Latin as the standard, and a stone monument is erected. The inscription is carved in five languages: Manchu, Han, Russian, Mongolian and Latin. Under this treaty, Russia lost the Okhotsk Sea but established trade relations with the Daqing Empire. This treaty divides Russia and China with the Xing 'an Mountains and the Erguna River as the boundary, but does not determine the ownership of the area between the Xing' an Mountains and the Udi River. On September 7, 1689, China and Russia held a grand signing ceremony. Soetu and Golovin first signed and sealed the treaty, then read the oath and exchanged the treaty with each other. This treaty is the "Nibchu Boundary Treaty." To celebrate, the two sides exchanged gifts and held a grand banquet. Comments: Unfortunately, it was signed in vain
