I don't see Botswana or Namibia as a poor countries. South Africa should not be a poor country but tribalism divisions and corruption keep that country down sadly .
Bots ordered a lot of Moderna vaccines months ago we had to pay above-market prices ( which seems to be the case with African countries who want to order the Vaccines ) that order to the allocated to Bots went to the EU . Still waiting here . China gives the first dose of Sinovac free to African countries .. and is winning the hearts and minds of people here .
No wonder ppl here are wary of the west .
African countries always get a sh!t deal, pay overs and then they postpone the delivery. Botswana should sue. Not sure exactly how Botswana is going now but I remember many years ago I taught development theory in a Masters course and I used to ask which 3rd world country had the highest growth rate from, I think, about 1965 to 1980 - the answer was Botswana. Small population, exporting diamonds, did well for a while but disadvantages such as small population again, but also landlocked so there are issues. Must go there one day, have been to South Africa (3 months in Jo'burg, and what a pleasant place it is!) many years ago.
Of course, if there's money to be made, Africa suddenly becomes out Indian Ocean neighbour.
