Poland will no longer arm Ukraine as it focuses on building its own arms stockpile, the prime minister said Mateusz Morawiecki, while Warsaw's attitude towards Kyiv changes just a few weeks before the elections.

Poland has been one of Ukraine's staunchest allies since Russia invaded the country in February 2022, but the countries have been at odds over Ukrainian grain exports since Warsaw extended a ban on them.

"We are no longer transferring any weapons to Ukraine because now we are arming ourselves with the most modern weapons," Mateusz Morawiecki told Polsat News.

Morawiecki's words came after Poland summoned Ukraine's ambassador to the foreign ministry to protest President Volodymyr Zelensky's comments following Poland's decision to extend the grain ban.

The ban was put in place to protect Polish farmers from a surge of grain and food imports from Ukraine after the Russian invasion largely blocked Ukraine's routes through Black Sea ports.

Zelensky told the United Nations General Assembly that Kiev was working to preserve land routes for grain exports, but added that the "political theater" surrounding grain imports was only helping Moscow.

Poland, Slovakia and Hungary announced restrictions on grain imports from Ukraine on Friday after the European Commission decided not to extend a ban on sales to five EU countries, including Romania and Bulgaria.

Poland holds parliamentary elections on October 15, and the ruling nationalist Law and Justice (PiS) party has come under fire from the far right for what it says is the government's submissive attitude towards Ukraine.

Ukraine's foreign ministry called for calm in the dispute on Wednesday, with a foreign ministry spokesman urging Poles to "put aside their emotions".
