The move comes after Ukrainian President Volodymyr Zelenskyy was stripped of Poland’s top honour.

Top Ukrainian officials have said they are returning Polish awards after President Volodymyr Zelenskyy was stripped of Warsaw’s top honour in a dispute between the allies over World War II massacres.

Zelenskyy’s chief of staff, Kyrylo Budanov; Ukraine’s ambassador to Warsaw, Vasyl Bodnar; and Foreign Minister Andrii Sybiha said on Saturday they would relinquish awards bestowed by Poland.

“Our nations have long-standing relations and ⁠different pages of history – both ⁠heroic and tragic,” Budanov posted on social media. “However, this should be an occasion for deep reflection, not crude political speculation.”

Zelenskyy angered many in Poland over his naming of a military unit after a Ukrainian paramilitary organisation accused of massacring Poles during World War II.

In a decree on May 26, Zelenskyy named a military unit the Ukrainian Insurgent Army (UPA) – the name of a group that operated in the 1940s and 1950s.

On Friday, Polish President Karol Nawrocki announced he would strip Zelenskyy of the Order of the White Eagle, which was bestowed on him by Former Polish President Andrzej Duda in 2023 for services to security, resilience and the defence of human rights.

For most in Poland, “the Ukrainian Insurgent Army remains above all a formation responsible for cruel crimes against the citizens of the Polish Republic during World War II,” Nawrocki said on social media, adding that the decision would not end Poland’s support for Ukraine against Russia.

Ukrainian officials criticised the decision as one that played into Russia’s hands. Budanov, the Ukrainian Presidential Office chief, wrote on Telegram that it was “an unfriendly act toward our people” and “a gift to the Moscow aggressor, which will certainly use it against both of our countries”.

Foreign Minister Sybiha called it a “strategic mistake” while Bodnar said it was “especially painful” as Ukraine fends off Russian attacks.

Polish Prime Minister Donald Tusk, a political rival of President Nawrocki, urged both sides to “calm tensions” in a post on X on Friday.

Conflict between Poland and Ukraine “delights Putin and shocks our allies”, he said.

The UPA fought against both Nazi German and Soviet forces, but is also accused of mass killings of Poles in Nazi-occupied areas. Ukrainians say UPA and Polish underground forces launched large-scale attacks and reprisals against each other that led to deaths among Ukrainian and Polish civilians.
