I suspect the real situation is way more complicated than what Jerome describes. The Trade he describes fits well with 'the Russian way of doing things', and I have little doubts it is happening. However I find it hard to believe Ukraine has never paid Gazprom anything - that would be too blatant even for Russia. There must be conflicting forces at play... I dont think we'll ever learn what actually is going on behind the stage.

PS. Your Russian is quite terrible, but definitely understandable ;)
