Foreign Minister of Ukraine Pavlo Klimkin is convinced that the legislative acts will not help in establishing the historical truth.

"Historical truth has no national borders and is not established by laws. It either exists, or it must be looked for. And in either case, legislative acts will not help Poland," he wrote on his Twitter page on Wednesday.

The minister also assured that he would always adhere to the truth. "I will always tell the truth. I will respect those who deserve it, condemn those who dishonored themselves, it doesn't matter insiders or outsiders, whether in Warsaw, Kyiv or elsewhere," the diplomat added.

As reported, the Senate of Poland adopted early on February 1 without any amendments the law on the Institute of National Remembrance, which foresees, in particular, punishment for "crimes of Ukrainian nationalists."

The bill was supported by 57 senators, mainly from the ruling Law and Justice (PiS) Party, 23 voted against the document, and two abstained. Amendments to the law envisage fines or imprisonment for up to three years for "sharing responsibility before the Polish people or the state, including for crimes committed by the Third Reich."

In addition, the document envisages punishment for denial of the "Volyn massacre" and the use of the expression "Polish death camps" in relation to the camps that were located in Poland during the Second World War. The law will enter into force after signing by Polish President Andrzej Duda.

President of Poland Andrzej Duda signed on February 6 amendments to the law on the of the Polish Institute: The Institute of National Remembrance – Commission for the Prosecution of Crimes against the Polish Nation. Thus, the changes previously approved by the Parliament came into force.

Earlier Duda said that he planed to appeal to the Constitutional Court of Poland with a request to assess the innovations. Thus, according to media reports, the president does not rule out that the law can still be modified.

President of Ukraine Petro Poroshenko said that he was concerned about the decision of the Senate of Poland.

As reported, on February 6, the Verkhovna Rada adopted a statement that expresses disappointment and concern over the adoption of amendments to the law on the Institute of National Remembrance - Commission for the Prosecution of Crimes against the Polish Nation and other legislative acts, and also called on Polish President, Andrzej Duda, to intervene in the situation.

"We are urging the president of the Republic of Poland [Andrzej Duda] to exercise his constitutional powers and, together with the Sejm and Senate of the Republic of Poland, to return balance, rationality and well-wishing to the Ukrainian-Polish relations," the statement says.
