To my understanding the majority of it isn’t privatized, but rather run by state-owned corporations. Is it for-profit, when being sold elsewhere? Of course, that’s just good business (and no doubt the Chinese arms industry is little different- arms sales are arms sales). And there would have been no reason, even if Russia had remained the USSR, to send freebies to such a deeply compromised country as Ecuador of all places (the fact that the subject of this thread- Ecuador trying to send arms to bloody Ukraine of all things- exists should be proof enough- this is a completely dollarized country as well, let’s not forget). But the development, production lines, etc… that all is geared to serve the interests of the state, not the interests of capital (hence why Russia is vastly outproducing the entire west in munitions, and why they retained such capacity till now).

In regards to suing and sanctioning Ecuador for trying to send their Russian-manufactured arms to Ukraine though- that also is just basic common sense. What country- regardless of economic system, privatization or state corporation, for-profit or otherwise, would not?
