More than 190 countries and 50 international organizations registered to participate in the 2010 Shanghai Expo.
After the six-month run, the Expo had attracted well over 70 million visitors.
The concept and design were contributed by the German communication agency Triad Berlin Projektgesellschaft.
The company, which had already designed a pavilion for the Expo 2000 in Hanover, won an international bidding contest against more than 150 competitors.
Construction was completed in September 2009 before interior construction began.
