The US public debt is denominated in Dollars, does the Saudi manufacture Dollars? If not, how could then they finance the public debt?

[LatteLazy]

They sell oil for dollars. They give the dollars to the fed and 101 other institutions as loans, those institutions lend the money to the government and private groups.

China does the same only they sell goods for dollars instead of oil.
