Russian wheat exports are expanding further across the globe as the world’s biggest shipper edges out competitors. shipments to Sudan have jumped 87 percent so far this season, turning the African country into the seventh-largest customer for Russian wheat. Sudan imported no Russian wheat until 2014, when millers decided the grain met their quality requirements. Such shifts among consumers, along with a third straight bumper crop and a weakened ruble, have allowed Russia to send wheat grown in the Black Sea region to markets as far away as Indonesia. That’s cut into the market shares of traditional suppliers including the U.S., the European Union and Australia.
