Ukraine’s military has suspended operations at its ports after Russian forces invaded the country by land and sea, an adviser to the president’s chief of staff said on Thursday, as concerns grew about the flow of supplies from one of the world’s top exporters of grains and oilseeds.
Russia had earlier suspended movement of commercial vessels in the Azov sea until further notice, but kept Russian ports in the Black Sea open for navigation, its officials and five grain industry sources said.
Russia and Ukraine account for 29% of global wheat exports, 19% of world maize (corn) supplies, and 80% of world sunflower oil exports.
