I can't believe nobody has noticed this about Wakanda yet Klaue got his arm in wakanda (or at least the vibranium for it). He is from the Netherlands.Bucky received a new vibranium arm from Wakanda. He is from America, but also lived in Siberia for some time.If my math is correctWakanda is an international arms dealer.ETA: Killmonger was not setting them up to be arms dealers, he just saw that they'd only dealt so few arms, and decided to ramp it up!
