Russian presidential aide Sergei Prikhodko said the two leaders will also attend an interregional cooperation forum dedicated to transport infrastructure development, border trade and environmental problems.

He added that Monday`s meeting, which is the ninth between the two presidents, is a stage in the preparation process for the November session of the Russian-Ukrainian intergovernmental commission.
