Russia agreed to a two-month extension of a deal that has allowed Ukraine to ship grain through the Black Sea to parts of the world struggling with hunger, a boost to global food security after the war drove up prices. Extending the Black Sea Grain Initiative is a win for countries in Africa, the Middle East and parts of Asia that rely on Ukrainian wheat, barley, vegetable oil and other affordable food products, especially as drought takes a toll. The deal helped lower prices of food commodities like wheat over the last year, but that relief has not reached kitchen tables.
