The Chicago fair, the first to have its own theme, demonstrated America's leading position in science and technology and also forecast the quick recovery of the U.S. economy.
Starting from 1935, almost every U.S. economic indicator took off on a road of stable growth. By 1939, the country's GDP had grown to 204.9 billion dollars from 7.42 billion dollars in 1933. The number of unemployed workers fell to 8 million.
In the same way, the Shanghai World Expo is also expected to showcase the new trends and developments in the global economy and build confidence in the world's economic future.
At the same time, China, the host country, has been applauded by the world for maintaining a sound economy during the financial crisis.
The fair, as is indicated by its theme "Better City, Better Life," will showcase the direction of future development for mankind, prompting countries to seek the common goal of sustainable development. A green economy is widely expected to become the new growth engine of the world.
