Gen. Nikolai Makarov, the chief of the Russian Armed Forces General Staff, will arrive in Poland on two-day working visit on Tuesday, the Russian Defense Ministry has said.

During the visit, Makarov is expected to discuss Russian-Polish military cooperation, as well as relevant international and European security issues, with his Polish counterpart Mieczyslaw Cieniuch, the ministry said in a statement.

On Wednesday, Makarov will visit a paratrooper base in Krakow. In Warsaw, the Russian delegation will visit The Tomb of the Unknown Soldier, the Soviet Military Cemetery, and the Powazki Cemetery, where they will pay tribute to Franciszek Gagor, the former chief of the Polish Armed Forces General Staff.

Gagor was on board the Polish presidential plane that crashed in western Russia in April, claiming the lives of all 96 passengers, including President Lech Kaczynski and his wife.

Russian and Polish experts are jointly probing the causes of the deadly crash, while Polish military prosecutors are conducting their own investigation.
