From the article:
“Wakanda’s upstream, midstream and downstream mineral sector are entirely controlled by Wakanda itself,” points out Nicola Woodroffe of the Natural Resource Governance Institute, a think-tank in London. It is as if Botswana not only mined, cut and polished diamonds, but also designed and produced the world’s diamond necklaces, drills and bearings. It is as if Norway had a monopoly on oil, petrochemicals and plastics.
Wakanda sounds more like North Korea than Botswana or Norway.
