To put it in context, that's enough grain to feed 272,000 people (2100 calories a day) for a year.

Edit: Some cargo ships can carry that much grain in one go. It would take 6x 100 car trains to move the same amount of grain over land.

This is such a dumb move... It achieves NOTHING in the war itself, only hurts non conflict countries that already struggle with hunger and poverty.
