　　On 21 June, starting at 9.30am CEST, each of the five candidates will make final presentations of their Expo projects to the 172nd General Assembly of the BIE. Eligible and present Member States of the BIE, represented by government-appointed delegates, will then vote for the Specialised Expo 2027/28 host country. Each Member State has one vote, in a secret ballot using electronic voting.

　　In any round of voting, the host country is elected if it receives a two thirds majority of the votes of present and eligible Member States. If no candidate is elected outright, further ballots are organised and the candidate with the least votes is eliminated after each round. If only two candidates are left, the candidate that receives a simple majority of votes cast will obtain the right to host the next Specialised Expo.

　　Expos are global events that explore a chosen theme through engaging and immersive discoveries. Among the different categories of Expos, Specialised Expos are designed to respond to a precise challenge facing humanity and may take place in the interval between two World Expos. Specialised Expos are limited in terms of duration - lasting up to three months - and space - with the exhibition area not exceeding 25 hectares. The site is entirely built by the Organiser, Participants being provided with pavilion space.

　　The most recent Specialised Expo,Expo 2017 Astana, took place in the capital of Kazakhstan under the theme “Future Energy”, and received almost 4 million visits.
