Nekula said that calls to ban Ukrainian grain imports were “populist” and not necessary. He also said that just 4,000 tons of wheat were imported into Czechia annually, which is less than 0.1 percent of total domestic production.
Some of Czechia’s bordering countries have banned imports to protect their own farmers, as the import of Ukrainian grain has seen a fall in prices of wheat and other products. Poland, for example, claims that Ukrainian grain is of inadequate quality due to potential contamination.
Since mid-May 2022, the price of one bushel (about 35 liters) of wheat has fallen from CZK 300 to CZK 148 now.
