Russia has halted a wartime deal allowing Ukraine to ship grain. It’s a blow to global food security

Russia halted a breakthrough wartime deal on Monday that allows grain to flow from Ukraine to countries in Africa, the Middle East and Asia where hunger is a growing threat and high food prices have pushed more people into poverty.

Kremlin spokesman Dmitry Peskov said Russia would suspend the Black Sea Grain Initiative until its demands to get its own food and fertilizer to the world are met. While Russia has complained that restrictions on shipping and insurance have hampered its agricultural exports, it has shipped record amounts of wheat.

“When the part of the Black Sea deal related to Russia is implemented, Russia will immediately return to the implementation of the deal,” Peskov said.

The suspension marks the end of an accord that the U.N. and Turkey brokered last summer to allow food to leave the Black Sea region after Russia’s invasion of its neighbor worsened a global food crisis. The initiative is credited with helping lower soaring prices of wheat, vegetable oil and other food commodities.

Ukraine and Russia are both major global suppliers of wheat, barley, sunflower oil and other affordable food products that developing nations rely on.
