My guess is that it will not work out well for them. In Africa in particular there have been riots near farming land owned by Chinese cooperatives. The Chinese pillage the land and ship all the food produced there to China. leaving the local population hungry and benefiting only a few big honcho's who're paid off.
Once Chinese nationals are killed or attacked the CCP will most likely send in troops to protect the Chinese workers, which in turn will lead to even more resentment and a call for their expulsion. It will be difficult for African leaders to ignore those calls.
The Chinese may end up with some worthless IOU's and a badly damaged reputation.
