Ukraine and Poland called in the ambassadors from each other's countries on Tuesday as a dispute escalated after a foreign policy adviser to Poland's president said Kyiv should show more appreciation for Warsaw's support in its war with Russia.
The adviser, Marcin Przydacz, also said the Polish government must defend the interests of the country's farmers - a reference to a ban on imports of Ukrainian commodities which will expire next month.
"What is most important today is to defend the interest of the Polish farmer," Przydacz was quoted as saying.
He also said: "I think it would be worthwhile for (Kyiv) to start appreciating what role Poland has played for Ukraine over past months and years."
Kyiv and Warsaw have been firm allies throughout the conflict that erupted with the Russian invasion of Ukraine in February 2022. But the exchanges reflected contentious issues.
Ukrainian foreign ministry spokesperson Oleh Nikolenko said the Polish ambassador was told in the meeting that statements about Ukraine's alleged ungratefulness for Poland's help were "untrue and unacceptable".
"We are convinced that the friendship between Ukraine and Poland is far deeper than political pragmatism. Politics should not question the mutual understanding and strength of relations between our peoples," Ukraine's MFA said in a statement at its website.
"No statements will prevent us from jointly fighting for peace and building a common European future."
Poland also called in the Ukrainian ambassador to Warsaw in response to the "comments of representatives of Ukrainian authorities", Poland's Ministry of Foreign Affairs wrote on the X platform, formerly known as Twitter.
The tweet did not specify what comments it referred to.
The European Union in May allowed Poland, Bulgaria, Hungary, Romania and Slovakia to ban domestic sales of Ukrainian wheat, maize, rapeseed and sunflower seeds.
After the Russian invasion blocked Black Sea ports, large quantities of Ukrainian grain, which is cheaper than that produced in the EU, ended up staying in Central European states due to logistical bottlenecks, hitting prices and sales for local farmers.
The five countries want the ban on grain imports to be extended at least until the end of the year. It is set to expire on Sept. 15.
Poland's prime minister said earlier this month that it would not lift the ban on Sept. 15 even if the EU did not agree on its extension.
Kyiv has described the Polish decision as "unfriendly" and urged Ukraine's partners and the European Commission to ensure the unimpeded export of all Ukrainian agriculture products to the EU.
The Polish foreign ministry did not respond to a request for comment on Tuesday.
