Bordering the East China Sea and at the estuary of the Yangtze River, Shanghai Pudong New Area is situated at the junction of China's "golden coast" and "golden waterway." Covering an area of 522 square kilometres, it has a population of about 1.4 million.  In April 1990 the Chinese Government declared an important policy of developing and opening-up Pudong, which has attracted the world attention. After more than ten years' development, with a mint of money from overseas fed into the mammoth construction in the Pudong area, remarkable achievements have been made, of which the four key zones have become the vanguard of developing and opening-up in Pudong. These four key zones include Lujiazui Financial and Trade Zone, Jinqiao Export Processing Zone, Zhangiiang High-tech Park Zone, and Waigaoqiao Free-Trade Area.
    
Since 1970s, especially since 1980s, for the fast development of New Pudong Zone, three big Bridges and four underwater tunnels have been built between Shanghai's Pudong and Puxi (the city proper of Shanghai).  To residents and visitors alike, set amidst the Huangpu waters formed by the Suzhou Creek and the Yangtze River estuary is acknowledged as one of the most beautiful and bustling cities in the world.
