The export of agricultural goods has been paralyzed in some parts of the Black Sea. The Russian defense minister has banned shipping across the Vsov Sea. This means that important ports such as Berdyansk and Azov, as well as Taganrog can no longer be approached. The most important Russian port in Novorossiysk reports that grain is still being transshipped there. Both countries account for almost a third of global wheat exports. For corn it is about 19%.
