I know virtually nothing about this situation, but as always, take what comes out of Moscow with a grain, or perhaps a pound, of salt (same goes for Constantinople too, by the way).
Here's a link which attempts to explain what's happening. I have no idea if it is accurate but at least it doesn't seem polemical.

This seems to be the salient part of the wikipedia article.
