Russia's so desperate to get its billionaires and their massive wealth back that it just threatened to seize the assets of an oligarch worth $13 billion

• Russia filed a lawsuit against oligarch Andrey Melnichenko, who is worth $13 billion.
• The lawsuit alleges Melnichenko's purchase of power plant operator Sibeco five years ago was corrupt.
• The state is looking to seize Sibeco amid Putin's call for Russian tycoons to invest at home.

Russia appears to be going ham on its billionaires lying low overseas as Moscow grapples with supporting its economy amid the war in Ukraine.
