On November 22, 2012 Astana was chosen by the International Exhibitions Bureau (BIE) as the venue to host EXPO-2017, which will focus on future energy issues. The theme of Future Energy is aimed to concentrate on both the future of energy but also on the potential energies of the future. Kazakhstan is very aware that the time has come for the world to move from fossil fuels to more sustainable energy sources. The selection of Astana to serve as host city is especially notable, because EXPO-2017 will be the first time that a major international exhibition of this kind is coming to a country from the former Soviet Union. More than 100 countries and 10 international organizations are expected to participate. Around 2- 3 million people are expected to visit the international pavilions from June to September 2017.
