The most relevant outside-of-Sudan consideration is Saudi Arabia. Muhammad bin Salman has boatloads of money invested in Sudan and Sudan is a country under Saudi influence.
I didn't realise this until I worked in Africa.
The black countries in West Africa are heavily controlled by Arabs. Without calling the Lebanese and Saudi's corrupt, once an African country is beholden to their money, it's almost impossible for the country to break free. Libya were guilty of this as well with Gaddafi. He would control the oil in Africa to great personal effect.
It's always interesting to hear about us Anglos working in far-flung biomes in potentially shady industries. When did you work in Africa, and in what area? Did it have to do with mineral or fuel extraction?
