On top of that, Russia probably is concerned that they have few global strategic partners and is on the hunt for allies wherever they can find them. Although Rwanda probably can't help out in too many places (eg. additional ports in Africa like the Chinese and other are trying to secure in places like Djibouti) it is still part of the UN and could help project power in the region & serve as an example of the kind of support Russia can give to Africa. I think in S. Africa they're trying to engage in military partnerships and recently sent a few bombers down.

Do you mean they're helping their domestic peaceful nuclear energy industry grow?

They probably are, it still helps them project geopolitical power, maybe earns them some money (although who knows, it may be mostly free and they get something else in return). Plus, a somewhat educated guess tells me that even their domestic peaceful nuclear industry is closely related to the highest levels of government and follows their strategic goals just as the military would.

It is a mutually beneficial deal. Nobody's "helping" anyone here.

The "help" is the government supporting a private enterprise. Cronyism that "helps" the political class and the company, but possibly not Russian citizens. Or maybe it does. Maintaining a domestic nuclear industry is certainly strategic.

All big strategic companies are supported by their respective governments one or the other way. Nothing is wrong about it. And the Government will have their cut in return eventually. I think it helps Joe Schmoe in the end as well.
