The Baltic states, Poland and Romania on Friday called on other European countries to make a bigger contribution to prevent historic manipulations by investigating Stalinist and Nazi crimes.
A joint statement by the foreign ministers of Lithuania, Latvia, Estonia, Poland and Romania released on the 80th anniversary of the Molotov-Ribbentrop Pact, states that "the practice of investigating and prosecuting the crimes of totalitarian regimes has been insufficient and inconsistent across countries".
"We call upon the governments of all European countries to provide both moral and material support to the ongoing historical investigation of the totalitarian regimes. By acting in a concerted manner, we can counter more effectively disinformation campaigns and attempts to manipulate historical facts," the statement reads.
The statement calls to prevent the revival of authoritarean ideologies, and "promote historical justice".
Lithuanian politicians and diplomats have long expressed their resentment over the lack of proper understanding of Soviet crimes in the West, and Russia's attempts to deny or belittle them.
On August 23, 1939, the Nazis and Soviets signed a secret pact and divided Eastern Europe, which led to the occupation of the Baltic states.
At the initiative of Lithuanian and other Eastern European countries, the European Parliament declared this day the European Day of Remembrance for Victims of Stalinism and Nazism.
