This wikipedia list from 2017: https://en.wikipedia.org/wiki/Net_international_investment_p...
has some interesting trends:
1) US is far down below in the list as a net debtor country with the NIIP being 43.4% of its GDP
2) Many erstwhile developing countries like China, India, Nigeria are slowly getting closer to the 0 mark twards net creditor status
3) Venezuela is a net creditor country with NIIP beign 30.5% of the GDP. How does that work for a country that's internally collapsing? Is it from historical oil lending deals to other countries?
