well,guy,
1. you are overreacted.
I am talking about the feazibility of a fair trillion-$ win-win deal, land for fund,not a scam or west-style loot based on gun and cannon
If the generious offer is not accepted by others, CHinese would just let them be and not break into and set up colonies as shameless west guys did centuries ago.
2. you are underesitimate the greedy of humankinds and the power of money...and overestimate the sense of pride of hunman kind,including Africans.
frankly speaking,
if you were to offer ordinary people additional 100-years salary and one new modern apartment as the relocation compensation, I am sure that 90% of them would be happy to accept it,whoever is a west guy, Russian, CHinese,indian ,African or Japanese,
