In March 1970 Japan hosted the World Exposition in Osaka. Subtitlted, “76 Countries and 1 administrative zone…”, the exposition was conspicuous for many reasons not the least of which was that it was the first world expo held in Asia in the nearly 100 years since the event’s origin in The Crystal Palace. If the event was so significant, why then did it take place under such a cumbersome and inauspicious subtitle? Official guidebooks for the expo described it as a showcase for “76 countries, four international institutions and one administrative district”. 1 The “administrative district,” sometimes translated simply as “a colony” was Hong Kong. Expos had become become stages on which nations negotiated technological, architectural, social, and cultural decisions to continually form and re-form their national identity. Tacking on Hong Kong was nothing if not a complicated gesture. Hong Kong was nearly two-thirds through its clearly delineated time as a colony of the British. At the end of that time a new era would begin as China would take the islands back into its own sovereign fold. In the long history of expos, however, Hong Kong’s identity was fluid, its various representations contested, its legibility never guaranteed, its positive reception always in the balance. Whatever the legal status of Hong Kong, World Expos were a place where its identity could shift some.
