Relocation

World leaders, including Nicolas Sarkozy, the French president, attended the opening ceremony.
The Chinese government spent eight years and more than $50 billion preparing for Expo Shanghai 2010, the country's first world's fair, which aims to showcase the latest technology and inventions through innovative or radical national "pavilions".
The main site has been designed to be environmentally friendly with the creation of the country's largest solar plant and the use of zero-emission vehicles. However, most of the pavilions will be demolished after October 31, when the Expo ends.
The government also had to relocate thousands of people for the Expo, some forcefully, according to rights groups.
"The Shanghai Expo authorities should be mindful that many remember the 2008 Beijing Olympics as much for the arrests and detention of peaceful protesters and journalists as for the achievements of the athletes," Sophie Richardson, the Asia advocacy director at Human Rights Watch, said.
Al Jazeera's Divya Gopalan, reporting from Shanghai, said despite the billions of dollars that had gone into preparing for the Expo, more than what was spent for the 2008 Beijing Olympics, there is more to the event than meets the eye.
"This event is not only about showcasing China's economic strength, it's also about showing the country's strength on the diplomatic front," she said.
"Leaders of countries are here to build ties with China with the view to improving their monetary status and their diplomatic relations.
"If a country chose to not come to this event, it would be regarded as a snub towards China. As a result we have seen 189 countries, ranging from the US and Germany to North Korea and financially troubled Iceland and Greece, come to Shanghai, and many of them have spent lots of soccer jerseys money on pavilions to show their support to China."
