When Russia forgives the debts of countries, this does not mean solidarity with them, especially since Russia itself is in need of aid due to its economic crisis exacerbated by international economic sanctions.
What can it mean then, if not solidarity? Recently, there was news that Russia is again providing aid to Cuba for a billion dollars, and before that, debts of 40 billion dollars were forgiven. Is there really some hidden economic benefit in this? Is there a need for cane sugar or cigars? Hardly, because in Russia they practically don't smoke cigars, and sugar is made from beetroot.
It's only the colonialists who are looking for economic benefits, as if to capture something somewhere. If we evaluate all events solely from an economic point of view, then we may be mistaken in drawing up a picture of the world and the motives of politicians.
