Andrzej Duda said his stance on the issue was the same as that of the Polish government.
The World Holocaust Forum is scheduled to take place on January 23 at the Yad Vashem Holocaust Memorial in Jerusalem.
Speaking at a special meeting with Polish government ministers in Warsaw on Tuesday, Duda said he had been invited to the World Holocaust Forum but, unlike Russian leader Vladimir Putin, had not been invited to speak.
Duda has previously said that he needed “to be able to speak alongside other presidents” in order to present the “historical truth, which, unfortunately, has been falsified recently.”
Russian President Putin recently reportedly suggested that Poland was partly responsible for the outbreak of World War II and claimed that the Soviet Union helped “save lives” after it invaded Poland in 1939 following a pact with Nazi Germany.
The comments triggered anger in Warsaw. Duda on Tuesday accused Putin of “post-Stalinist revisionism” and of trying to shift the blame for the outbreak of World War II onto Poland.
Meanwhile, Polish Deputy Foreign Minister Paweł Jabłoński said earlier on Tuesday: “It is unacceptable, at a conference dedicated to the Holocaust, for Vladimir Putin to be one of key speakers and for Poland's president not to be able to speak.”
