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.
