Ok, man, that's awesome.
As for Pan-African Nation, I haven't been able to think of much. What I have thought is that it's got enough firepower to be a serious threat to anybody who tries something dumb like taking it over, and that it has Mombassa (well, *New* Mombassa) as a capital.
(Doesn't exactly means it'd win, just that it'd be a serious fight if it happened).
I was thinking that it has connections with Wakanda, but they are pretty much built on the fact which Cortana mentioned rather easily to Black Panther that it's just *not* a good idea to have the PAN as an enemy. If they don't want to trade Vibranium and be chatty neighbors, ok, sure, no problem. But they are surrounded by folks who wouldn't have much of a problem bombing the whole damn country flat and kill everybody in it if they piss them off (and Vibranium... well, it's hard to find on Earth, yeah, but it's not impossible to find elsewhere if you look hard enough (like off-world mines, some of which have been making a killing in the Rare Earth Minerals market, or manufactured (which, well, won't be as good as the pure stuff, but a Vibranium brake disk doesn't needs to be like Captain America's shield)), and just as good if not better than the Wakanda version, or at least in larger quantities).
So (Cortana says in a sickly-sweet voice while batting her eyelids) maybe not acting like a bunch of a*****es and at least saying 'hello' every once in a while is just the best way to go from this day onwards...
