World Expo Shanghai yesterday launched a worldwide search for exhibition designs for China National Pavilion.

The 20,000-square-meter China Pavilion will explore the theme "Chinese wisdom in urban development" by explaining traditional Chinese values about harmony, nature and spirit.

Winning entries will be published mid-April next year.

China's pavilion will be the highlight of the 2010 Expo, so the exhibition plan should be of high quality, said the organizers. Applicants must show excellent ideas and a unique presentation.

China's section of the Expo will house the national pavilion, a joint pavilion for provinces and cities, and separate pavilions for Hong Kong, Macau and Taiwan.

Provinces and cities will get 600 square meters each to showcase their varied traditions.
