The treaty was signed on 9 January 1792 by Grand Vizier Koca Yusuf Pasha and Prince Bezborodko (who had succeeded Prince Potemkin as the head of the Russian delegation when Potemkin died). The Treaty of Jassy formally recognized the Russian Empire's annexation of the Crimean Khanate via the Treaty of Küçük Kaynarca of 1774 and transferred Yedisan (the territory between Dniester and Bug rivers) to Russia making the Dniester the Russo-Turkish frontier in Europe, and leaving the Asiatic frontier (Kuban River) unchanged.
