LONDON -- The European Union on Friday decided not to renew a ban on Ukrainian food heading to nearby countries that have complained that an influx of agricultural products from the war-torn nation has hurt their farmers.
The move sets up a clash with Poland, Slovakia, Hungary and Romania, which have said that food coming from Ukraine has become stuck within their borders, creating a glut that has driven down prices for local farmers and hurt their livelihoods.
The issue threatens European unity on supporting Ukraine against Russia's invasion.
Poland's Prime Minister Mateusz Morawiecki reacted by saying that his government will extend its own ban on Ukrainian grain, regardless of any lack of consent from the European Commission, the EU's executive arm. Officials said the measure would be published Friday.
"We will do that because it is in the interest of Polish farmers," Morawiecki said during a campaign rally ahead of Oct. 15 parliamentary elections in which the governing Law and Justice party is trying to attract farmers' votes.
Bulgaria, while part of the original ban, decided this week to allow in Ukrainian imports again to bring down food prices.
"The market distortions" have disappeared, according to the European Commission. Ukraine has agreed to put measures in place starting today to control the export of wheat, corn, rapeseed and sunflower seeds to neighboring EU countries, the commission said in a statement.
It also will introduce proposals -- for example, an export licensing system -- within 30 days to avoid grain surges, the EU said.
Hungary also has threatened to adopt its own ban on Ukrainian agricultural products if the EU didn't act.
Without an EU extension, "then several countries banding together in international cooperation -- the Romanians, the Poles, the Hungarians and the Slovaks -- are going to extend the import ban on a national level," Hungarian Prime Minister Viktor Orbán said in a radio interview on Friday.
In a turnaround, Bulgaria lawmakers on Thursday approved resuming imports of Ukrainian food products. Finance Minister Asen Vassilev says the ban has deprived the government of tax revenue and led to higher food prices.
Ukraine praised Bulgaria's decision and had pressed for an end to the ban, saying any further restrictions would have "a clear destabilizing effect on the global food market," Ukraine's Ministry of Foreign Affairs said in a statement.
Grain and other Ukrainian food had been allowed to pass through the five European countries on the way to parts of the world in need.
In July, Russia pulled out of a U.N.-brokered deal allowing Ukraine to ship grain safely through the Black Sea. Routes through neighboring countries have become the primary way for Ukraine -- a major global supplier of wheat, barley, corn and vegetable oil -- to export its commodities to parts of the world struggling with hunger.
Recent attacks on Ukraine's Danube River ports have raised concerns about a route that has carried millions of tons of Ukrainian grain to Romania's Black Sea ports every month.
That has meant road and rail routes through Europe have grown increasingly important. While facing blowback from neighbors, they aren't ideal for agriculture-dependent Ukraine either, whose growers face higher transportation costs and lower capacity.
After the countries passed unilateral bans earlier this year, the EU reached a deal allowing them to prohibit Ukrainian wheat, corn, rapeseed and sunflower seeds from entering their markets but still pass through their borders for export elsewhere.
The EU also provided an additional $113 million in special aid on top of an initial support package of $60.2 million to help farmers in the affected countries.
