The Bureau of International Expositions, based in Paris, picked Buenos Aires over rivals Bloomington, Minnesota, and Lodz, Poland, to host a specialized World Expo in 2022-23. It will be the first expo in Latin America under the auspices of the BIE, which began operations in 1931. Minnesota was seeking to host the first world's fair on U.S. soil in almost 40 years. The Trump administration has sought to boost American interest in world's fairs, events that introduced the world to the Eiffel Tower, the Ferris wheel and Seattle's Space Needle. Full-scale World Expos that last six months are now held every five years, while three-month expos devoted to specific themes take place in intervening years. Buenos Aires made showcasing artistic and technological innovations its theme. Minnesota proposed a specialized expo on the theme "Healthy People, Healthy Planet.'' The bid theme from Lodz focused on the revitalization of post-industrial cities. Argentina's organizers hope the event will attract at least 6 million visitors. Dubai, in the United Arab Emirates, is set to host the next full World Expo in 2020.
