"During the visit, the sides will sign an additional agreement delineating the Russian-Chinese border in its eastern sector," the ministry said in a statement.
Earlier this month, a senior Russian security official said that Russia would in August relinquish control of the Tarabarov Island and about half of the Bolshoi Ussuriysky Island, located at the confluence of the Amur and the Ussuri rivers, under a 2004 bilateral agreement.
Russia and China signed border agreements in 1991 and 1994 delimiting the eastern and western sections of their frontier, but issues over several minor sectors were left unresolved.
The two islands - occupied by the Soviet Union in 1929 and referred to collectively in Chinese as the Heixiazi - were the site of several military skirmishes between the two powers during the 1960s.
The 2004 agreement on the eastern sector of the 4,300-kilometer border, the world's longest land frontier, was signed after China agreed to drop territorial claims to islands near the Russian city of Khabarovsk.
During his visit, Lavrov will meet with Chinese leader Hu Jintao, Premier Wen Jiabao of the State Council, and Foreign Minister Yang Jiechi "to discuss urgent issues of international and regional politics."
