The Katyn massacre, energy cooperation and missile defense will dominate the agenda when Russian President Dmitry Medvedev meets with his Polish counterpart Bronislaw Komorowski next week.
Medvedev will visit Poland on December 6-7.
The results of the talks promise to be "very positive," Medvedev's aide, Sergei Prikhodko, said.
"The sides are determined to strengthen the current positive tendencies in bilateral ties and to significantly improve them in all areas," Prikhodko said.
Medvedev and Komorowski will give their assessment of the probe into a plane crash that killed Polish leader Lech Kaczynski and 95 dignitaries in April. They were on their way to a memorial ceremony in honor of thousands of Polish officers killed at Katyn near Smolensk by Soviet secret police.
The lower house of Russia's parliament declared last week that Soviet dictator Joseph Stalin and other Soviet officials ordered the massacre in 1940.
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 offices.
Agreements on energy cooperation, trade and investment cooperation are also in the offing.
