Subsequently, the participating countries will offer similar advantages to introduce from time to time every few years.

　　Today EXPO is the economic and cultural Olympiad of the world, a competition among nations, as well as among exhibitors from the private sector on a given subject. At the same time, it is about marketing countries internationally. Expositions of the first category last a maximum of 6 months and may be held on an enormous area. But at a time when information as well as goods can be had through the internet and other technologies, they remain a place of rendezvous and of authentic experiences.
