Specialised Expos

Specialized Expos (formally known as International Recognized Exhibitions) are usually united by a precise theme—such as "Future Energy" (Expo 2017 Astana), "The Living Ocean and Coast" (Expo 2012 Yeosu), or "Leisure in the Age of Technology" (Brisbane, Expo '88). Such themes are more specific than the wider scope of world expositions.

Specialized Expos are usually smaller in scale and cheaper to run for the host committee and participants because the architectural fees are lower and they only have to customize pavilion space provided free of charge from the Organiser, usually with the prefabricated structure already completed. Countries then have the option of "adding" their own colours, design etc. to the outside of the prefabricated structure and filling in the inside with their own content.
