Wu, chairman of the National People's Congress Standing Committee, said at a ceremony that the government would spare no effort in preparation for the 2010 Shanghai World Expo, and the country looked forward to experiencing technological advances and sharing the achievements of human civilization with friends from across the world.

The Expo could also help promote the development of civilizations and cultures, he said.
China's business hub, Shanghai, won a bid to host the 2010 World Expo in 2002. The Expo will be on stage from May 1 to Oct. 31 next year.

The countdown timer was installed at the east side of the square, where a similar timer once counted down the days to the Beijing Olympic Games. After the Expo opens, the timer will display the daily number of visitors.
Wu said the Expo would help increase exchanges and cooperation between China and the rest of the world.

The top legislator also said that a successful, splendid and memorable World Expo was a promise made by the Chinese government and people.
Shanghai's Communist Party chief, Yu Zhengsheng, who is also the vice-chairman of the Expo's organizing committee, said at the ceremony that the fair would be another international event in China after the Beijing Olympic Games, for which all preparations went smoothly.
The Expo would also be a safe and frugal event, Yu added.
