A one-sided article. They don't mention:

• Ukrainian military burns down the harvest when they have to retreat (literally leaving scorched earth)
• There are open and de-mined ports (Mariupol is one of them)
• The Ukrainian government tried to convince the Turkish government to stop ships with grain from the separatist republics
• The Russian marine cannot protect all ships with Russian grain.

But that's ZeroHedge - they don't publish balanced articles, instead they publish two articles with different points of view.

That grain is Russian grain now.
