The host of the 2030 World Expo will be chosen on Tuesday, with Rome in Italy, the Saudi capital Riyadh and South Korea’s Busan contending to welcome the showpiece event held every five years.
The World Expo — which traces its history back to the 1851 Great Exhibition in London and the 1889 Exposition Universelle in Paris that saw the construction of the Eiffel Tower — is a months-long mega event attracting millions of visitors that aims to respond to the specific challenges of the current time.
