Poland’s prime minister said his country is no longer sending arms to Ukraine as a trade dispute between the neighboring states escalates and his populist party faces pressure from the far right in the upcoming national election.

Iran PressEurope: Poland will no longer send weapons to Ukraine, Polish prime minister Mateusz Morawiecki has said, in an escalation of tensions between Warsaw and Kyiv that threatens the west’s unity in supporting the country as it battles Russia’s invasion.  

A row over grain exports has triggered a significant rift between Ukraine and Poland, one of its staunchest supporters in Kyiv’s war with Russia. On Wednesday, Prime Minister Mateusz Morawiecki said Warsaw will no longer transfer weapons to Ukraine and will instead focus on ensuring its own defense with the arsenal of modern arms it recently purchased.

The trade dispute comes after the European Union last week decided against renewing a ban on Ukrainian grain heading to nearby countries, including Poland, which have claimed their farms will be hurt by an influx of agricultural products from the war-torn country.

Poland’s threat came after Warsaw, alongside Hungary and Slovakia, last weekend unilaterally extended an import ban on Ukrainian grain, even after Kyiv promised to ensure its exports would not harm EU farmers. That provoked a backlash from Ukrainian officials, led by President Volodymyr Zelenskyy.
