Grain producers in Bulgaria have called for a halt to imports of Ukrainian wheat. Protesters taking part in demonstrations in three Bulgarian regions told state radio BNT that domestically grown wheat cannot compete with Ukrainian imports, which are around 30 percent cheaper. "The market has collapsed, the warehouses are full," the coordinator of the protests, Dimitar Dimoitrov, said on March 13, adding that there were similar problems as a result of the import of cheaper sunflower seeds from Ukraine.
