Shanghai is one of the largest cities in the world with over 24 million people. It is the financial capital of China and a city of extreme historical significance. Shanghai is considered the crowning achievement of China's economic success in recent years, and showcased this success when it hosted the World Expo 2010.
Shanghai's identity has been shaped by its history, which can be traced back thousands of years. It has been a market city since the mid 11th Century and became a trading center for the world in 1842. By 1930, Shanghai was a world hub of trade and commerce. Much of Shanghai's success was originally due to its proximity to the coast and Asia's largest river, the Yangtze. However, China recently re-invested in Shanghai in the early 1990's as a center for world finance, which has seen rapid ecenomic growth in a short period of time.
