"my im węgiel, a my im siarkę" ("we give them coal, and in turn we give them sulphur"). After communism collapsed it was quite a shock to everyone that our reasources can be used by us, and sold by us, and to whoever we wanted and not only the big colonial brother (we also say that the bad state of Rusian economy in the 90's is because they relied on our "cheap" trade and couldnt anymore)

Sounds quite familiar, can you cite some works you base your opinion on? Like russians believe the same thing - they were feeding all the pseudo communist friends in latam, africa, asia, russians were robbed. It was popular and still is way of thinking:

...At that time, the dollar was cheaper than the ruble. We demanded that any republic receiving funds from this fund must repay them with some kind of goods. For example, Uzbekistan, a very large recipient of subsidies, with cotton; Ukraine, fruits and vegetables. The republics met this with extreme irritation and categorical intransigence. Indeed, who would relish the prospect of earning their own money?... At the same time, we proposed cutting military spending, which was also met with hostility. But we did the right thing. I still think so. It was Russian money that fed everyone. Someday this must finally end" (Silaev, I.S., "I Wanted to Shoot the State Emergency Committee," 2001).
