I worry they don’t need wwii levels.

China takes Siberia. Soon. And maybe Taiwan.

Colonize it while it remains nominally Russian, would be a pretty good move. "Sick Man of Europe"-style. "Oh we British are just, just, like, helping the Ottomans administer Egypt, we're good chaps like that"

No need... if things continue the way they are, they'll soon be offered the opportunity to buy Siberia
