Lujiazui is an important financial district in Pudong, Shanghai. In 2005 the State Council reaffirmed the positioning of the 31.78 km2 Lujiazui area, as the only finance and trade zone among the 185 state-level development zones in mainland China. Currently, there are more than 30 buildings over 25 stories high with commerce as their leading function, and over 504 domestic and overseas financial and insurance corporations located in Lujiazui. The success of Pudong in the past 20 years has fueled tourism and business related travel to Shanghai.
