WARSAW, Poland (AP) — Poland and Israel have summoned each other's diplomats in a growing dispute over Poland’s planned changes to property restitution rules that Israel and Jewish organizations say would prevent Jewish claims for compensation or property seized during the Holocaust and communist times.

On Monday, Israeli charge d ’affaires ​Tal Ben-Ari Yaalon met with Polish Deputy Foreign Minister Pawel Jablonski, who insisted the new regulations do not bar any property claims, which should be made through courts. Poland also says it mustn't be made responsible for property seizures by Nazi Germany during its World War II occupation of Poland.

“These regulations are not directed against anyone,” Jablonski said, adding that there is a lot of misunderstanding of their aim as they give the law a steady framework.

Jablonski later said Ben-Ari Yaalon repeated the embassy's statement from last week, which called the new regulations “immoral" and said they “will have a serious impact” on bilateral relations.

Poland’s ambassador to Israel, Marek Magierowski, was at the Israeli Foreign Ministry on Sunday, explaining the new regulations made to align with a 2015 ruling by the top constitutional court.

Poland’s parliament is processing the changes to prevent ownership and other administrative decisions from being declared void after 30 years. It says this is a response to fraud and irregularities that have emerged in the restitution process. The changes still require approval from the Senate and the president.

The World Jewish Restitution Organization said it was “deeply disappointed” by Poland's response to the concerns.

"The house or shop or factory in a town in Poland affected by this legislation was not taken by Germany, it was taken by Poland. It sits today in Poland and its use has benefited Poland for over 70 years. It is time to recognize this fact and for Poland to do justice for those who suffered so much,” said the group's chief, Gideon Taylor.

Last week, the U.S. State Department weighed in, with spokesperson Ned Price tweeting that the changes were a “step in the wrong direction” and urged Poland “not to move this legislation forward.”

Before World War II, Poland was home to Europe’s largest Jewish community of some 3.5 million people. Most were killed in the Holocaust under Nazi Germany’s occupation and their property was confiscated. Poland's post-war communist authorities seized those properties, along with the property of non-Jewish owners in Warsaw and other cities. The end of communism in 1989 opened the door to restitution claims, most of which would be coming from Poles.

The still unresolved matter has been a constant source of bitterness and political tension between Poland and Israel.

In 2001, a draft law foreseeing compensation for seized private property was approved in parliament but vetoed by President Aleksander Kwasniewski. He claimed it violated social equality principles and would hurt Poland’s economic development, implying that compensation claims would result in large payouts. He also said individual claims should be made through the courts.

Poland is the only European country that has not offered any compensation for private property seized by the state in its recent history. Only the remaining communal Jewish property, like some synagogues, prayer houses and cemeteries, mostly in disrepair, have been returned where possible or compensated for.
