The World Expo is a large-scale, global, non-commercial Expo. The hosting of the World Expo must be applied for by a country and approved by the international World Expo committee. Expo aims to promote the exchange of ideas and development of the world economy, culture, science and technology, to allow exhibitors to publicise and display their achievements and improve international relationships. Accordingly, the World Expo with its 150-year history is regarded as the Olympic Games of the economy, science and technology.
