Fernández Castaño, the Commissioner of the Expo, has explained that due to the characteristics of the International Exhibition, "Expo 2008 cannot house all of the countries of the African region, or in other words, their presence is the result of a previous selection process depending on the different institutional relations and the willingness of each country".
For me, what it matters is that the (collective) African pavilion, with space for 14 different countries, is representative and self-explanatory of the entire African continent water & sustainable development issues.
