No, not really. They showed Killmonger's neighbourhood and the project they were starting there, but Wakanda came out at a UN conference and talked about the world helping each other, which they now wanted to take part in. Also, Nakia was already helping internationally before that (which was the conflict between her and T'challa) and she wasn't in the US. You can doubt very much that she would have stayed with T'challa, had he agreed to only grant Killmonger's wishes and not hers.
