Celebrations spread across China when Shanghai, the Oriental Pearl, was given the right to host the 2010 World Expo on December 3. Shanghai won the honor after beating rivals from Russia, Mexico, Poland and South Korea.

“I’m very proud of being Chinese,” said Wang Kaibo, a Senior 2 student of the Middle School Affiliated (附属的) to Beijing Medical University. “The winning of the expo is a victory, not only for Shanghai residents, but for the people of the whole Chinese nation.”

Bidding for the expo shows that China is more confident of playing a more important role on the international stage. It’s competing for large events and the next one could be the World Cup, Wang said.

The World Expo 2010 and the 2008 Beijing Olympics will become the twin shining stars of China’s development over the next 10 years, said experts. The World Expo is known as “Olympics of the economic, cultural, scientific and technological fields.” It is usually held every five years and lasts for six months. The Olympics, World Cup and World Expo are considered three top international events in the world.

China is the first developing country to win the expo bid in the event’s about 159-year history. Not only will it attract more foreign investment to China, but experts say that the half-year-long exhibition will bring at least 70 million visitors to Shanghai.

The expo was first held in London in 1851. It has a history of global influence. The Eiffel Tower, built during the Paris World Expo in 1889, became the symbol of the French capital.Many historic inventions, such as the telephone and airplane, all made their first appearance at a World Expo.
