He literally states, and I quote, "to respect unity, territorial integrity and full sovereignty of all African Union member states including the Federal Republic of Somalia".Did the AU chairman suggest how the Somaliland status should be resolved? Nope.
Did he say it shouldn't be resolved by external actors? Nope
So you can see that the US is actually holding a firmer line than the AU is.
Anyway. I can't be bothered. Look into these things in your own time.
You are arguing semantics at this point, just because they didn't explicitly state that Somaliland isn't allowed to be recognized by others doesn't mean they don't agree with the deal or that America is forcing them to say those things.
