Warsaw has stopped supplying weapons to Kyiv and is focusing on arming itself instead, Polish Prime Minister Mateusz Morawiecki said Wednesday, amid a dispute over Ukraine’s agricultural exports.

“We are no longer transferring weapons to Ukraine, because we are now arming Poland with more modern weapons,” Morawiecki said in an appearance on the Polish television channel Polsat, according to European Pravda. “If you don’t want to be on the defensive, you have to have something to defend yourself with,” he added, insisting, though, that the move wouldn’t endanger Ukraine’s security.

Morawiecki’s terse comments came as tensions escalated between Kyiv and the EU over the past week after the European Commission moved to allow Ukrainian grain sales across the bloc, ending restrictions on grain imports which five eastern EU countries originally sought to protect their farmers from competition.

Poland, Hungary, and Slovakia responded to the Commission’s move by imposing unilateral bans on Ukrainian grain imports, in apparent violation of the EU’s internal market rules. Kyiv struck back by filing lawsuits against the three countries at the World Trade Organization.

Ukrainian President Volodymyr Zelenskyy on Tuesday took a thinly veiled swipe at those imposing grain bans, telling the U.N. General Assembly: “It is alarming to see how some in Europe, some of our friends in Europe, play out solidarity in a political theater — making a thriller from the grain. They may seem to play their own role but in fact they are helping set the stage to a Moscow actor.”
