In China, a move by a local unit of Sinograin to ban smartphones and cameras from its granaries has provoked national worries about levels of reserves. A cellphone video that showed moldy and dirty grain at a granary went viral in recent days, reports the South China Morning Post. “China corn video stokes food security fears amid coronavirus pandemic, flooding and drought,” headlines the story. In recent years, Ukraine was the largest supplier of corn to China. But to redress its trade balance with the US, China recently bought 3.9 million tons of corn from the US, the US Department of Agriculture reported Thursday.
