The Ukrainian Economy Ministry said on Monday that Kiev had filed lawsuits with the WTO against Poland, Hungary and Slovakia because of their prohibition on the import of Ukrainian products. On Tuesday, the WTO told Sputnik that Kiev has submitted a complaint to the organization, asking for consultations regarding the said ban on the import of Ukrainian grain to Poland, Slovakia and Hungary.
Later on Wednesday, Polish Prime Minister Mateusz Morawiecki warned that Warsaw would expand the list of import bans from Ukraine if the neighboring nation would further escalate the spat. He added that Poland had rebuffed all lawsuits and other legal proceedings brought against it, while accusing Kiev of failing to grasp how much Poland's farming industry was being destabilized.
On September 15, the European Commission announced it would lift the ban on duty-free Ukrainian grain imports to five member states bordering Ukraine, as well as a demand that Kiev introduce export controls. Following the decision, Poland, Hungary and Slovakia announced that they were unilaterally extending the ban. In response, Kiev threatened to prohibit the import of certain goods from Poland and Hungary if they failed to remove the grain embargo.
