Ukrainian grain exports fell by 55.5 percent in the first 20 days of June compared with the same period in 2021 to 777,000 tonnes, the country’s agriculture ministry data showed on Monday.

The volumes included 689,000 tonnes of corn, 63,000 tonnes of wheat and 21,000 tonnes of barley, the data showed.

Ukraine exported up to 6 million tonnes of grain a month before Russia launched a "special military operation" on February 24.

Volumes have since fallen to about 1.7 million tonnes as Ukraine, which used to export most of its goods through seaports, has been forced to transport grain by train via its western border or via its small Danube river ports.
