[3] By the end of the expo, over 73 million people had visited – a record attendance – and 246 countries and international organizations had participated.
In 2004, the Chinese central government established the Shanghai World Expo Organising Committee as the organization dedicated to host the event.
Shanghai began clearing 2.6 square kilometres along the Huangpu River; that involved moving 18,000 families and 270 factories, including the Jiang Nan Shipyard, which employs 10,000 workers.
[citation needed] Shanghai trained more than 1.7 million volunteers and adopted Olympic-level security measures, adding metal detectors to subway entrances and screening cars entering the city.
During 2010's Spring Festival, Shanghai received 2.79 million tourists, an increase of 12 percent from the previous year, resulting in record high numbers of visitors.
The event featured an outdoor display of fireworks, lasers, and dancing fountains after a performance by singers and dancers.
[16] About 20,000 performances were set to be staged between 1 May and 31 October in 2010, many singers present at the expo song writing and preparation process since 2008.
Performers included Alan Tam, Gigi Leung, Stephanie Cheng, Khalil Fong, Hacken Lee, Denise Ho, Hins Cheung, Vincy Chan, Philadelphia Boys Choir, National Boys Choir of Australia, Salut Salon, the Cross Border Orchestra of Ireland and the Harvard Din & Tonics, and others.
[22] The main building – called "Expo Axis" – has the world's largest membrane construction[23] and was built by SBA (architects) and Knippers Helbig (structural engineers).
[25] National pavilions included: Algeria, Angola, Argentina, Australia, Austria, Bangladesh, Belarus, Belgium, Bosnia and Herzegovina, Brazil, Brunei Darussalam, Canada, Cambodia, Chile, China, Colombia, Costa Rica, Croatia, Cuba, Czech Republic, Denmark, Dominican Republic, Ecuador, Egypt, Estonia, Finland, France, Germany, Greece, Hong Kong, Hungary, Iceland, India, Indonesia, Iran, Iraq, Ireland, Israel, Italy, Japan, Jordan, Kazakhstan, Kenya, Kyrgyzstan, Latvia, Lebanon, Libya, Lithuania, Luxembourg, Macau, Macedonia, Malaysia, Malta, Mexico, Monaco, Mongolia, Morocco, Myanmar, Nepal, Netherlands, New Zealand, Nigeria, North Korea, Norway, Oman, Pacific Pavilion, Pakistan, Palestine, Peru, Philippines, Poland, Portugal, Romania, Russia, Saudi Arabia, Serbia, Singapore, Slovakia, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Taiwan, Thailand, Timor-Leste, Tunisia, Turkey, Turkmenistan, Ukraine, United Arab Emirates, United Kingdom, United States, Uruguay, Uzbekistan, Venezuela, Vietnam and Yemen.
[27] San Francisco (a Shanghai sister city) was one participant here,[27] as were Dafeng Town in Shenzhen, Hangzhou, Liverpool, London, Montreal, Rotterdam and Seoul.
[31] The Shanghai Expo was touted by the Chinese government as yet another first-rate global scale event, similar in significance to the Beijing Olympics, which would symbolise the economic and political rise of China in the 21st century.
[32] Outside China, the Expo propelled Shanghai onto magazine covers, newspaper front pages and television programmes at a time when it is laying the groundwork to become an international financial centre by 2020.
[35] According to the U.S. government-run Congressional-Executive Commission on China, Shanghai authorities used the expo as an excuse to conduct a surveillance, propaganda, and detention campaign against members of the banned Falun Gong spiritual group.
[36] Denmark controversially sent the original Little Mermaid statue from Copenhagen to the expo, putting a video replica recorded by dissident Ai Weiwei in its place.
[38] Six legislators from the pro-democracy camp boycotted an invitation to the expo by the Shanghai government because of the issue of political reform and the 2010 Hong Kong by-election.
[40] State employees were given free one-day vouchers to the expo, and according to one worker, threatened with wage cuts, in order to fulfill the target of 70 million visitors.
