Ukraine’s forecast bumper crop for corn may run into geopolitical barriers as the US makes record corn sales – totaling 3.7 million tons — to China, warns AgWeek, the Fargo, North Dakota-based news site. China made the record buys of US corn to comply with a Trump Administration drive for more balanced US-China trade. Although Ukraine traditionally ships 3.8 million tons of corn to China every year, “that might not be the case this year,” warns AgWeek. China already has purchased enough corn to cover 80% of this year’s needs.
