I looked for Ethiopian or African news sites that confirm this story, but it seems like it's not accurate. This African green news site only mentions that ICE cars will be phased out in line with the EU by 2035 and that the government encourages the sale of electric cars through incentives and local assembly:

There is nothing on this on any large Ethiopian news site. The Reporter has no article on this:

Neither does The Ethiopian Monitor:

This Senegalese outlet states that it's not clear when the ban comes into effect:

Given that there are significant issues with maintaining and insuring existing electric cars in the country, it's safe to assume that the ban will not happen immediately:

There is a different car import ban since October of last year aimed at returning citizens, which doesn't appear to have anything to do with the move to electric vehicles though:

So in other words, this awful article containing a chat log for some reason (What on Earth was the author thinking with that?) is just an example of poor reporting.
