Sigh.
The WFP is, of course, free to buy Russian grain to replace the Ukrainian grain it bought- and it did buy it, though you'd be excused for thinking they didn't and it was given away by the language used in some reports. ie Good Guy Russia, wfp has more money to buy grain since they now only have to supply ~20% of the amount to Africa they used to. Which, and this left me flabbergasted amazed and bewildered, wasn't actually 725kt.
In a Very Surprising turn of events western media included amounts sent to non African countries (Afghanistan, Yemen) and one country that already has a replacement deal with Russia (Ethiopia) in their figures. Indeed, supposedly the 4 biggest receivers of WFP food aid were: Ethiopia, Turkey (!, presumably earthquake related), Afghanistan and Yemen (via wsj, but it's paywalled) and the only African country there is Ethiopia. Somalia is also western aligned, at least in theory.
And, of course, the AU head's comments can very easily be read as criticism of the west for trying to stifle Russia's food exports. And yes, I know there's a lovely EU page saying they aren't doing that, it just leaves out every bit where they are. Which the Africans are very much aware of.
And and once again again, if Europe and the US really wants to help Africa and stick it to Russian agricultural exports they could skip a few collective burgers. Then there would be plenty of cheap food and a lot less leverage. That takes some self control though, eh.
