"Direct losses for Ukraine's agricultural sector could reach between $1.5 billion and $3 billion this year," he said. Purchase prices for oilseeds and grains have declined by an average of 30% in Ukraine, the minister noted. Since July 22, the ports of Odessa, Chernomorsk and Yuzhny have not received or shipped a single foreign cargo ship. International companies refuse to work with them for security reasons and reorient cargo transportation, for instance, to the Romanian port of Constanta. Logistics problems pushed Ukrainian grain purchase prices so low that many farmers are forced to sell their crops at a loss.
