I believe it is Russia. They are at less than 1% of USA's debt. Don't quote me but I think USA has a debt of ober 8or 9 trillion whereas Russia's debt is about 70 or 80 billion. ...Incredible, huh?
There are a bunch of little Pacific Island 3 acre countries with like 400 to 5000 dollar debt. No joke
I don't think it is Russia. It is Maxico. From report of UN Maxico is the first number in debt Ratio. But they declare previous report...so it can be changed in current year.
Well it depends on the % of Debt as a gross national product. Look at this.
