This is part of the US decoupling ( Gradual trade sanctions ) with China
in anticipation of a full blown "proxy" war with China over Taiwan where
as someone already commented, that Taiwan will be another Ukraine.
China has already "American-proofed" itself by:
-the BRI
-developing USD free trade with the BRICS
-defence against US enforced trade sanctions in shipping
(South China Sea militarised artificial Islands)
-The ports of Gwatar and Djabouti & the new Suez Canal as Chinese Naval bases to protect
shipping choke points to the Red Sea & the Persian Gulf.
The only remaining choke point is the Malacca .
IMO this Ukrainian war has simply advanced US plans to have a serious
go at China to stymie its economic growth and if possible break it
up into a rabble of rump states and with it debunk the CCP.
That may not be as easy as US Hawks think and such extreme
moves by the US could very well be its own undoing, IMO.
IF the USD is knocked off its Reserve currency perch , then
the US mountain of debt is enough to sink it without this
Ukrainian proxy (Russian) war or a later Taiwan/China (US/China proxy war)
I note with interest that Taiwan was included with the Ukraine & Israel
in the recent US war funding bill.
But of course even any pleb realises that the US simply can't accruing national
debt at this rate .
