UN Secretary-General António Guterres described the agreement signed in July as an "agreement for the world", which enabled the export of grain from the Ukrainian Black Sea ports.
Russia had made a commitment to the United Nations to allow cargo ships carrying grain and sunflower oil to leave Ukraine.
The agreement, signed in Istanbul, ended a five-month blockade of Ukraine's ports by Russia.
But now the Kremlin is showing the world once again how little it cares about keeping to the contract.
The agreement would have expired on November 19, and the Kremlin didn't even want to wait that long.
An easily transparent pretext had to be used at the weekend to terminate the agreement prematurely.
The Kremlin doesn't care much about contract compliance
This denunciation is another example of how Russia honors and disregards international obligations at will.
She didn't come unexpectedly.
On the one hand, Russia had repeatedly indicated that it was not prepared to extend the agreement, and on the other, Ukraine complained that Russia was deliberately delaying exports.
The Russian leadership apparently wants to punish uninvolved third parties for the fact that their army is failing to achieve its war goals in Ukraine and is increasingly getting on the defensive.
War against civilians beyond Ukraine
For three months, the agreement had alleviated the food crisis in many countries.
Just because the Russian leadership wants it, they are now threatening to return with full force before the winter.
Just as the Kremlin is waging a war against the civilian population in Ukraine by destroying energy infrastructure, so it is also waging a war with starvation weapons against the poorest in the third world, where food prices will now rise even more.
Talking morally to a man like Putin will not get us anywhere.
However, Guterres and Turkish President Erdogan should do everything they can to persuade him that the agreement remains in force.
