Russia and Poland have a common stake in building mutual trust, Russian Prime Minister Vladimir Putin said in a message to the Polish people on Constitution Day.
"I am sure that the peoples of our two countries, who recently together went through a tragic event, are interested in the strengthening of mutual trust and understanding," Putin said in a congratulatory telegram to his counterpart, Donald Tusk, a government statement said.
"The widening of genuine friendly and mutually-advantageous relations between Russia and Poland is likewise important from the point of view of the guarantee of stability and security in Europe," he added.
Polish President Lech Kaczynski was killed in a plane crash on April 10 near the west Russian city of Smolensk. He was on his way to a ceremony to pay tribute to the some 20,000 Polish officers killed by Soviet secret police during World War Two in Katyn and other locations across the U.S.S.R.
This year will mark 20 years since Russian authorities first admitted that thousands of Poles were executed by the NKVD in "one of the gravest crimes of Stalinism."
