Shanghai whose name literally means "on the sea", is located on the East China coast just to the south of the mouth of the Yangtze River. It is the largest city in China and one of the largest urban areas in the world, with over 20 million people in its extended metropolitan area.
Originally a fishing and textiles town, Shanghai grew to importance in the 19th century due to its favorable port location and as one of the cities opened to foreign trade by the 1842 Treaty of Nanking.The city flourished as a center of commerce between east and west, and became a multinational hub of finance and business by the 1930s. However, Shanghai's prosperity ground to a sharp halt after the 1949 Communist takeover and the subsequent cessation of foreign investment. After being allowed economic reforms in 1990, Shanghai is booming once more with intense development and financing, and today, Shanghai is not only an important centre of commerce and finance, but also a popular place for Yangtze River cruise or even China tours. One conference paper has refered to it as a future global city and the popular press have described it as the "showpiece" of the world's fastest-growing economy.
