Poland says it will no longer arm Ukraine and will instead focus on its own defense, as the two allies clashed at a key moment in Kyiv's fightback against invasion by Russia. In a mounting row over grain exports from Ukraine, Poland summoned the Ukrainian ambassador on September 20 to protest remarks at the UN by President Volodymyr Zelenskiy. The Ukrainian leader said some countries were only pretending to support his nation. Asked about the dispute, Polish Prime Minister Mateusz Morawiecki said, "We are no longer transferring weapons to Ukraine, because we are now arming Poland with more modern weapons."
