World Expo 2010, held along the banks of the Huangpu River in Shanghai, China, marked the first time that a World Expo theme focused on quality of life in cities. This gave the international community a unique opportunity to share their achievements and offer a comprehensive overview of the theme of “Better City, Better Life”. In those 184 unforgettable days, 246 countries and international organisations showcased their ambitious plans and creative ideas for urban development, making a significant contribution to the advancement of human civilisation and the sustainable development of cities. Beyond its physical impact on Shanghai, the spiritual wealth of the Expo is today seen in the creations of the Shanghai Declaration, most notably the Shanghai Manual and the establishment of World Cities Day.
