SHANGHAI, Oct. 31 (Xinhua) -- China staged a series of performances, parades and forums here Sunday to celebrate the end of the Shanghai World Expo, which International Exhibitions Bureau (BIE) President Jean-Pierre Lafon called an "astounding success."

The first of its kind staged in a developing country, the event attracted 246 participating countries and international organizations and 73 million visitors. Both figures are records in the history of expos, the first of which was held in London in 1851.

On an area of 5.28 square kilometers, the Expo Site has become a global village where people can not only see rare cultural treasures from around the world -- the bronze chariot and horse sculpture from China's Warring States period, the statue of Athena from Greece and French impressionist masterpieces, for example -- but also get a taste of the diversity of the world's cultures through more than 20,000 cultural events.

The gala is eyed in China as another event of national splendor after the 2008 Beijing Olympic Games showcased China's status as an economic and political power to the world.

It is also a milestone in both economic and social terms, bringing attention to the future of the planet, which is battling with poverty, war, pollution and energy shortages.

Chinese Premier Wen Jiabao declared the closure of the Expo at a ceremony Sunday evening. Before that, he said at the Summit Forum on the sidelines of the Expo the success of the Expo has boosted China's confidence and resolve to pursue reform and opening up.

"The Expo has brought together the Chinese people wishing to learn more about the world and foreign friends wishing to know more about China. Thanks to the Expo, they have forged a strong bond of friendship," said the Premier.
