The row was triggered by Ukrainian President Volodymyr Zelensky's decision to name a military unit after the fighters of the Ukrainian Insurgent Army (UPA), which during World II massacred ethnic Poles.
Zelensky said the naming was intended to honour the unit's battlefield performance and restore historical military traditions.
The move drew a negative response across Poland's political spectrum.
President Karol Nawrocki proposed stripping Zelensky of the Order of the White Eagle, Poland's highest state honour, awarded to him in 2023.
Prime Minister Donald Tusk called the decision "worrying", but suggested that Nawrocki's response was "a similar step" – and urged both presidents to "rise above historical emotions".
Czarzasty said Zelensky's decision warranted a response, but cautioned against acting out of emotion, warning against "ill-considered decisions" and arguing that Poland's long-term national interest lay in Ukrainian independence and EU membership.
Ukraine's parliamentary speaker Ruslan Stefanchuk thanked him for his "balanced and responsible position", saying the two nations must "look to the future together".
The opposition Law and Justice (PiS) party took a harder line, with its prime ministerial candidate Przemysław Czarnek calling Zelensky's move "a slap in the face" to Poland and demanding the government revive a shelved bill banning the promotion of Ukrainian nationalist ideology on Polish soil.
Poland and Ukraine have long disagreed over the legacy of the UPA.
For Poland, UPA actions in the Volhynia region in 1943, when tens of thousands of ethnic Poles were killed across scores of villages, constitute genocide.
Ukraine has historically viewed the UPA primarily as an anti-Soviet resistance movement, and regards the wartime conflict as one for which both sides bear responsibility.
