The only thing i agree with you is this: Chinese building of African projects is CURRENTLY better than American, British, European or Worldbank loans.
Loans are rarely ever used for the intended projects. Only, a minuscule part of the loaned funds are used to start the projects. The rest are split to offshore accounts, buy votes and grab more political power.
Do the loaners know that loan will go to waste? Yes and they hope it does. Why? Neo-colonization & Neo-slavery - illusion of independence.
Direct force is old fashioned and too costly. Subtle economic sabotage and puppetry is much better.
With loans, you can threaten debtor countries to depreciate their currencies. Use your multinationals to evaporate domestic competition, stunting their competitiveness. Extract their raw materials and dictate the price. Place of corrupt individuals in key offices and more.
Is China exploiting African countries? Absolutely. Ghanaian gold mining is basically Chinese.
Yet, conventional loans are like carrots placed in front of a horse, pulling it just before it bites. Think Charlie brown.
Chinese will build roads, bridges, airports, power plants instead of giving loans. Yes they'll give jobs to Chinese engineers but the project will be completed. - on time too.
Sure Chinese milk the cow dry but it will eat and grow fatter, instead of leaner.
