When the UN brokered the Ukraine Grain Deal struck in July 2022, the pivot to allow transportation thru the Black Sea was signed and sealed.   But the grain never reached its African destinations and instead went to Poland and eastern Europe.   Poland declared the grain was tainted –

April 2023, Poland, Hungary and Slovakia suddenly banned Ukraine grain imports into their countries.   The EU Commission threatened the countries for overstepping their EU authority on trade.   A deal was made that the imports throughout the eastern bloc would simply be transit lines and not destinations.  "It is also a success for other countries effected by the situation in the grain market and, I think, a success for the European Union."

The EU also agreed to pay Poland $40 million euros for their trouble.
