As in the past several world's fairs, various African nations will be exhibiting together in one hall. Nations incapable for funding their own exhibits are subsidized by the expo authority. Most African nations have modest exhibits, but there are sometimes hidden gems in their displays and with so many small nations, this is a great oportunity to talk with people from those countries and perhaps find out a bit more about countries you don't know much about. At the very least, you can fill up your passport quickly!
Egypt
One of the most anticipated pavilions by locals, it will be interesting to see what Egypt displays as they address the expo's theme of "Better City, Better Life."
Libya
Libya hasn't participated in many recent international expositions, but in Shanghai, they'll have their own building.
Morocco
Tangier, Morocco waged an unsuccessful bid for Expo 2012, losing to Yeosu, Korea. As a unique country with influences from many different cultures, it usually has very rich, immersive displays encompassing visuals, music, and aromas.
