Hangzhou ([xǎŋʈʂóʊ]), formerly romanised as Hangchow, is the capital and largest city of Zhejiang Province in Eastern China. It sits at the head of Hangzhou Bay, which separates Shanghai and Ningbo. Hangzhou grew to prominence as the southern terminus of the Grand Canal and has been one of the most renowned and prosperous cities in China for much of the last millennium, due in part to its beautiful natural scenery. The city's West Lake is its best-known attraction.
Hangzhou is classified as a sub-provincial city and forms the core of the Hangzhou Metropolitan Area, the fourth-largest metropolitan area in China. During the 2010 Chinese census, the metropolitan area held 21.102 million people over an area of 34,585 km2 (13,353 sq mi). Hangzhou prefecture had a registered population of 8,892,000 and the built-up area (including the 9 urban districts and the Keqiao and Yuecheng districts of Shaoxing) held 8,874,348.
In September 2015, Hangzhou was awarded the 2022 Asian Games. It will be the third Chinese city to play host to the Asian Games after Beijing 1990 and Guangzhou 2010. On November 16, 2015, President Xi Jinping announced that Hangzhou would host the eleventh G-20 summit on September 4–5, 2016.
