The rising tensions come after Russia halted a UN-brokered agreement last month to guarantee safe shipments of Ukrainian grain through the Black Sea to parts of the world struggling with hunger.
It has left more expensive road, rail and river routes through Europe as largely the only way for Ukraine, a major global agricultural supplier, to export its food products, though there have been some limited ship movements to its ports.
Bulgaria’s National Association of Grain Producers said in a statement on Sunday before the protests that farmers are facing “unprecedented difficulties” and called for a ban on a litany of food products from Ukraine.
These include sunflower, wheat, corn and rapeseed, as well as crude oil, meat, fruits and vegetables, milk, honey and dairy products.
Ventsislav Mitkov, chairman of the United Farmers National Association in Bulgaria, said at a protest in the western town of Pernik, about 30km from the capital, Sofia, that they want to ban “absolutely everything.
“Stop imports from Ukraine. We mean wheat, sunflower, canola, all cereals, honey,” he said. “We want increased control and immediate payment of the European measures.”
The EU said “the market distortions” created by Ukrainian grain have disappeared. But farmers in the five member countries, including Romania, still complain that a glut of Ukrainian products is hurting their livelihoods.
EU agriculture ministers met on Monday and urged unity.
“I understand that there are challenges in the neighbouring countries, but we need to tackle those challenges in a way that we are respecting the internal market rules and also the international trade rules,” Finland’s agriculture minister Sari Essayah said.
The protesters in Bulgaria have vowed to continue demonstrations until their demands have been met.
“Low-quality, cheaper products than ours are sold in the shops,” Vassil Dzhorgov, a farmer from the eastern town of Radomir, told The Associated Press.
“We are operating at a loss, and therefore we will give up.”
Ukraine agreed to put measures in place to control the export of wheat, corn, rapeseed and sunflower seeds to neighbouring EU countries.
It also will introduce proposals - for example, an export licensing system - within 30 days to avoid grain surges, the EU said.
