Poland’s top politician said Thursday that the government will seek equivalent of some $1.3 trillion in reparations from Germany for the Nazis’ World War II invasion and occupation of his country.

Jaroslaw Kaczynski, leader of the Law and Justice party, announced the huge claim at the release of a long-awaited report on the cost to the country of years of Nazi German occupation as it marks 83 years since the start of World War II.

“We not only prepared the report but we have also taken the decision as to the further steps,” Kaczynski said during the report’s presentation.

“We will turn to Germany to open negotiations on the reparations,” Kaczynski said, adding it will be a “long and not an easy path” but “one day will bring success.”

He insisted the move would serve “true Polish-German reconciliation” that would be based on “truth.”

He claimed the German economy is capable of paying the bill.

Germany argues compensation was paid to East Bloc nations in the years after the war while territories that Poland lost in the East as borders were redrawn were compensated with some of Germany’s pre-war lands. Berlin calls the matter closed.

Germany’s Foreign Ministry said Thursday the government’s position remains “unchanged” in that “the question of reparations is concluded.”
