It's helpful to think of the flow of capital acquired through privatization of Russian state property into US-based and EU-based businesses as a form of money laundering. It's about legitimizing these assets and moving them farther away from the source of their original dubious provenance. DST investments are yet another instance of that.

From the value perspective these investments don't seem to make much sense, but value is not the primary objective, or not the only objective in this case. It's also about legitimization and moving assets outside of purview of those who could potentially reclaim them.
