Zhejiang

Zhejiang is a coastal province in East China. Its capital and largest city is Hangzhou, with other notable cities including Ningbo and Wenzhou. Zhejiang is bordered by Jiangsu and Shanghai to the north, Anhui to the northwest, Jiangxi to the west and Fujian to the south. To the east is the East China Sea, beyond which lies the Ryukyu Islands. The population of Zhejiang stands at 64.6 million, the 8th largest in China. It has been called "the backbone of China" because it is a major driving force in the Chinese economy and being the birthplace of several notable people, including the Chinese Nationalist leader Chiang Kai-shek and entrepreneur Jack Ma. Zhejiang consists of 90 counties (incl. county-level cities and districts).

The area of Zhejiang was controlled by the Kingdom of Yue during the Spring and Autumn period. The Qin dynasty later annexed it in 222 BC. Under the late Ming dynasty and the Qing dynasty that followed it, Zhejiang's ports became important centers of international trade. It was occupied by the Wang Jingwei regime during World War 2. After the establishment of the People's Republic of China, Zhejiang's economy became stagnant under Mao Zedong's policies. After the reform and opening up, Zhejiang grew to be considered one of China's wealthiest provinces, ranking fourth in GDP nationally and fifth by GDP per capita, with a nominal GDP of US$1.27 trillion as of 2024.

Zhejiang consists mostly of hills, which account for about 70% of its total area, with higher altitudes towards the south and the west. Zhejiang also has a longer coastline than any other mainland province of China. The Qiantang River runs through the province, from which it derives its name. Included in the province are three thousand islands, the most in China. The capital Hangzhou marks the end of the Grand Canal and lies on Hangzhou Bay on the north of Zhejiang, which separates Shanghai and Ningbo. The bay contains many small islands collectively called the Zhoushan Islands.

Hangzhou is a historically important city, and is considered a world city with a "Beta+" classification according to GaWC. It includes the notable West Lake. Various varieties of Chinese are spoken in Zhejiang, the most prominent being Wu Chinese. Zhejiang is also one of China's leading provinces in research and education. As of 2025, three major cities in Zhejiang ranked in the world's top 130 cities (Hangzhou 10th, Ningbo 85th and Wenzhou 130th) by scientific research output, as tracked by Nature Index.
