Ukraine is desperately trying to export its vast stores of grain by road, river and rail to help avert a global food crisis but has no chance of hitting its targets unless Russia's blockade of its Black Sea ports is lifted, a government official said.
Before Russia sent troops into Ukraine on Feb. 24, the country had the capacity to export up to 6 million tonnes of wheat, barley and maize a month but exports collapsed to just 300,000 tonnes in March and 1.1 million in April.
