Wagner Group owns oil fields in Syria and mines in Africa. Wagner also is involved in contracts with the Russian state. That's who pays them lol.

The Wagner Group is a Russian private military company they've been backed by Russia to represent Russian interests but mercenaries will work for anyone who puts the money on the table.
You really think this happening right now while the EU is dishing out reconstruction contracts for the Ukraine is a coincidence?
I don't, but we can all believe whatever we want.
