Financing your friends and bankrupting your enemies is a strategy western nations perfected during the Cold War and employed to brutal effect in the immediate aftermath of the dissolution of the USSR.
But its not a trick that’s unique to western intelligence. Chinese officially had effectively bought out Hong Kong long before it transitioned into Beijing’s control.

Russia’s economic influence over Ukraine was a big part of what triggered the civil war in 2014 and the Crimea takeover that same year.
