Problemet er EU har fjernet det midlertidige forbudet mot Ukrainsk korn.
Men Polen protesterer fordi det truer den polske bonden.
"“We will extend this ban despite their disagreement, despite the European Commission’s disagreement,” Polish Prime Minister Mateusz Morawiecki told a rally on Friday. "We will do it because it is in the interest of the Polish farmer."
Det har ført til at Ukraina har klaget inn Polen til WTO (World Trade Organisation)
“While Ukraine appealed on Tuesday for a “constructive dialogue”, a World Trade Organization spokesperson confirmed that Kyiv had taken the first step in a trade dispute by filing a complaint to the global trade body.”
Det misliker polen sterkt, og sier de vil forsvare sitt importforbud.
"Duda said that if Ukraine filed the complaint, Poland would explain the situation before the tribunal.
He underscored that the ban regarded imports but not transit of Ukrainian grain.
“There are business circles that have interests in Ukraine and would like to sell grain as quickly as possible at the lowest possible cost. We have to defend ourselves against it,” he said."
Og den polske presidenten er også misfornøyd med at Ukraina trekker Polen inn for WTO tross all hjelpen Polen har gitt Ukraina i krigen mot Russland, og mener at Ukraina må bregense seg, og uttaler følgende om situasjon for å understreke alvoret:
“I would compare it to something like a drowning person… A drowning person is extremely dangerous because he can pull you to the depths … He can simply drown the rescuer.”
