The biggest problem Africa faces is from without not within. Granted we are seeing the end of the colonizers as we are establishing a World Order after 300 years of their pillaging and plundering and bloodsheding... but this transitional phase is going to tough. However, the good news is that with a World Order established and colonizers becoming insignificant and obsolete, the world as a whole can breathe once again and many countries including those in Africa can slowly start seeing peace which is the first step for development.
The attempts by African nations to gain true independence from colonizers have been met with stiff resistance. Terrorist attack on nations like Burkina Faso, Mali, and Niger increased when they decided to severe ties with France. This shows that there are clear indication of alliance between terrorist groups and these colonizers.
Take Sudan for example. The colonizers still want their resources and are stealing it by creating wars can chaos. Did you know back in March and April when Iran was heavily bombing all the US/NATO military bases across West Asia, the bloodshed in Sudan slowed down to halt? The Western proxies could not receive the munition from the colonizers (through the Zionist bin Zayed proxy) so they could not commit massacres in Sudan any longer and the Sudani forces finally managed to push them back liberating their cities during those months...
In this case it doesn't matter if Sudan has vast resources including one of the largest gold mines in the world. As long as there is foreign intervention by corrupt regimes trying to steal their resources, they won't see peace.
You made a good observation. One of the main rival group in the war is Rapid Support Forces (RSF) which is backed by the United Arab Emirates. Some of the major supplier of weapons to the UAE are South Korea, Israel and France. The RSF receive Western made weapons and drones from UAE which is used to commit atrocious in Sudan in order to have access to cheap raw materials.
Of course there are other important things needed to solve the fundamental issues. Such as a wise leader who can get people moving. Get them off their asses and make them believe in their capabilities and be able to fix years of brainwashing by the colonizers that has convinced them "they can't".
Elections are manipulated to give power to Western puppets. This is why revolutionary leaders are taking power by force. And we have seen considerable progress in countries that have decided to be truly independent.
