3. Egypt: With a diversified economy that includes tourism, agriculture, and a growing energy sector, Egypt has a significant GDP and plays a crucial role in regional politics and trade.

4. Algeria: Rich in natural gas and oil, Algeria’s hydrocarbon revenues make it one of the wealthiest countries in Africa. It has the 10th largest reserves of natural gas in the world.
