Chinese President Hu Jintao voiced confidence of Shanghai hosting an "unforgettable" World Expo on 30th April, which he said would bridge China and the world.

Hu addressed a welcoming dinner for foreign dignitaries who would attend the opening ceremony of the Shanghai Expo on Friday evening.

Hu and his wife Liu Yongqing shook hands with visiting foreign guests before the dinner.

"I am confident that, with concerted efforts, people around the world will witness a successful, splendid and unforgettable World Expo," said the President, giving a toast at the dinner.

In the past eight years, China has mobilized resources throughout the country and pooled the wisdom of the world, he said.

As the first registered World Expo hosted by a developing country, the Shanghai Expo will be "an opportunity for China and also for the world," Hu said.

At this Expo, China will present to the world a country with 5,000-year history, which is enjoying fast development and changes through reform and opening-up, he said.

The Expo will serve as a bridge for China to learn the good experience of other countries and engage in exchanges and cooperation with the rest of the world, he said.

A record number of 189 nations and 57 international organizations participate in the Expo in Shanghai, China's business hub.

In next six months, 70 million visitors are estimated to tour the Expo venues.

"The World Expo is a grand event to showcase the best achievements of human civilization. It is also a great occasion for people from around the world to share joy and friendship," he said.

It will offer a platform for all countries and regions to fully exhibit their achievements in urban civilization, share best practices and spread advanced ideas on urban development, he said.

"We will learn from each other, draw on each other's strengths and explore new models of housing, living and working for mankind in the new century," he said.

Hu said he believed this Expo would contribute to interactions and mutual learning between Chinese and people of other countries, as well as among different civilizations.

Hu pledged that China would make continued effort to improve the livelihood of its 1.3 billion people and make greater and new contribution to the world peace and development.

The country would remain committed to the path of peaceful development and a win-win strategy of opening up, he said.
