(simplified Chinese: 江苏; traditional Chinese: 江蘇; pinyin: Jiāngsū; Wade–Giles: Chiang-su; Postal map spelling: Kiangsu) is a province of the People's Republic of China, located along the east coast of the country. The name comes from jiang, short for the city of Jiangning (now Nanjing), and su, for the city of Suzhou. The abbreviation for this province is "苏" (sū), the second character of its name. It is the province with the highest population density in China, though provincial level municipalities like Shanghai, Beijing, and Tianjin have a higher density.
Jiangsu borders Shandong in the north, Anhui to the west, and Zhejiang and Shanghai to the south. Jiangsu has a coastline of over one thousand kilometers along the Yellow Sea, and the Yangtze River passes through its southern parts. Since the inception of economic reforms in 1978, Jiangsu has been a hot spot for economic development, and is now one of China's most prosperous provinces. The wealth divide between the rich southern regions and the north, however, remains a prominent issue in the province.
Jiangsu is home to many of the world’s leading exporters of electronic equipment, chemicals and textiles. It has also been China’s largest recipient of foreign direct investment since 2006.
