Shanghai is one of the four municipalities under the direct administration of the central government of China, the largest city in China by population, and the second most populous city proper in the world, with a population of more than 24 million as of 2017. It is a global financial centre and transport hub, with the world’s busiest container port. Located in the Yangtze River Delta, it sits on the south edge of the estuary of the Yangtze in the middle portion of the East China coast. The municipality borders the provinces of Jiangsu and Zhejiang to the north, south and west, and is bounded to the east by the East China Sea.
The Shanghai World Financial Center is a supertall skyscraper located in the Pudong district of Shanghai. It was designed by Kohn Pedersen Fox and developed by the Mori Building Company, with Leslie E. Robertson Associates as its structural engineer and China State Construction Engineering Corp and Shanghai Construction (Group) General Co. as its main contractor. It is a mixed-use skyscraper, consisting of offices, hotels, conference rooms, observation decks, and ground-floor shopping malls. Park Hyatt Shanghai is the tower’s hotel component, comprising 174 rooms and suites occupying the 79th to the 93rd floors, which at the time of completion was the highest hotel in the world. It is now the third-highest hotel in the world after the Ritz-Carlton, Hong Kong, which occupies floors 102 to 118 of the International Commerce Centre.
On 14 September 2007, the skyscraper was topped out and is 492 metres (1,614.2 ft), making it the 9th tallest building in the world and the fourth tallest structure in Mainland China.
