The Dutch Pavilion design, known as "Happy Street," is mainly composed of a pedestrian strip shaped like the number "8,” a lucky number in China that suggests fortune.

Twenty-six small houses will be elevated along the main pedestrian strip. The houses will present exhibitions exploring themes such as energy, water, space and many other urban issues.

Hong Hao, director of the Bureau of Shanghai World Expo Coordination, said he believed the pavilion would be one of the most interesting ones at Expo 2010.

The pavilion is expected to attract more than 7 million visitors, Balkenende said.

The country also signed a contract to participate the Expo Shanghai Online yesterday with the Shanghai Expo organizers.

Netherlands signed its participation contract with the organizers in November, 2007.
