I know about Chinese operators who will deliberately congest peering ports to influence 3rd party network behaviour.
How do they deliberately congest peering ports? Do you hear from those Chinese operators or you observe this from the traffic? Most countries in Africa do not implement great big firewalls. Our problems
are quite different :-\...
Not having great big firewalls tends to help :-).
Seems like you also think GFW is part of the cause, however, we don't have direct evidence. Just curious, What is your "problems"? I thought it's congestion.

(yes..., any minute is too long...)Indeed. There was a time when backhaul links between ISP routers at the exchange point and their nearest PoP were based on E1's, wireless, e.t.c. But that could be said of, pretty much, every exchange point that kicked off inside of the last 2.5 decades. Nowadays, such links, if they exist, are the very deep exception, not the rule. Mark.
