The Russian and Polish presidents, Dmitry Medvedev and Bronislaw Komorowski, will discuss the Katyn massacre, energy cooperation and missile defense in Warsaw on Monday.
Medvedev is starting a two-day visit to Poland on Monday.
The results of the talks promise to be "very positive," Medvedev's aide, Sergei Prikhodko, said earlier, adding that the sides are determined to strengthen the current positive tendencies in bilateral ties and to significantly improve them.
Medvedev and Komorowski will give their assessment of the probe into April's plane crash that killed Polish leader Lech Kaczynski and 95 dignitaries who were on their way to a memorial ceremony in honor of thousands of Polish officers killed at Katyn near the western Russian city of Smolensk by Soviet secret police.
The State Duma, the lower house of Russia's parliament, in late November recognized the 1940 massacre as a crime committed by Soviet dictator Joseph Stalin's regime. Poland welcomed the move.
The presidents are expected to seal several deals, including on the fight against pollution in the Baltic Sea and on cooperation between the countries' prosecutor's offices.
Agreements on energy, trade and investment cooperation are also in the offing.
Bilateral trade in January-September 2010 totaled $14.9 billion, a 40% rise year-on-year.
