China owns over $1 Trillion in U.S. Treasury bonds, and is the largest purchaser of them. People freaked out when Elon purchased 10% of Twitter, yet they aren’t concerned about China.
China only owns 7.5 percent of US Treasury Bonds.
Not a big deal.
That a drop in the bucket. Remember the petrodollar? The US has been exchanging T-bills for oil with the Saudis for over 50 years. The "Project Sandman" has 155 countries committed to purchase oil in their own currencies and repudiate use of the US Dollar. The Saudis will be looking for redemption of their T-bills in gold or tangible commodities. They won't accept the worthless fiat US Dollar in exchange for the T-bills.
