Debt trap, true.
But: If you own the bank 100 Dollar and︁ you can not serve this debt, it is you who has a problem.
If you︂ own the bank 1 Billion Dollar and you can not serve this debt, it is︃ the bank who has a problem.
In this case the bank is China and the︄ ones who can not pay are the 1-Billion-Dollar debtors.
Check Kenya, Ethopia, Sri Lanka, Zambia,︅ Argentina, Venezuela - all the same: In theory China owns these countries, in practice China︆ own nothing of them.
Anyway, this has not much to do with "Migration of︇ World's Millionaires", so I have to leave it here.
