Ship carrying Ukrainian grain

A ship carrying Ukrainian grain has left Odessa, bound for Lebanon.

If Putin allows grain shipments to continue, that will be a great help to many countries where people are suffering from hunger.

I previously suggested the idea that Ukraine could choke off Russia's oil exports from Novorossiysk. Back then, it would have been retaliation in kind for what Putin was doing — but maybe he is no longer doing that.

If Putin henceforth refrains from cutting off Ukraine's exports, Ukraine should and must refrain from cutting off Russia's exports.
