The construction of the China Pavilion for the 2010 World Expo in Shanghai is now in its key phase.

The China Pavilion covers more than six hectares and comprises three parts - the national hall, the hall for provinces and regions and the hall for Hong Kong, Macao and Taiwan.

Standing about 70 meters tall and red in appearance, the Pavilion takes the shape of an emperor's crown, with the upper levels larger than the lower ones.

As a permanent landmark in Shanghai's Pudong area, the structure will use ecologically sound technologies and energy-saving measures. These include its sun-shading design, using the exterior of the domestic pavilion as a buffer zone for heat or cold, as well as landscaping on the roof.

The project is expected to be completed by September, 2009 and will be used for conventions, exhibitions and business once the expo ends.
