The politics of Jiangsu Province in the People's Republic of China is structured in a dual party-government system like all other governing institutions in mainland China.
The Governor of Jiangsu is the highest-ranking official in the People's Government of Jiangsu. However, in the province's dual party-government governing system, the Governor has less power than the Jiangsu Communist Party of China Provincial Committee Secretary, colloquially termed the "Jiangsu CPC Party Chief".
Under the Qing dynasty, the governor (巡撫, xunfu) of Jiangsu was the highest-ranking official within Jiangsu but reported to the Viceroy of Liangjiang, who was often involved in provincial affairs. Additionally, the taotais of the treaty ports were often quite autonomous and exercised a great deal of influence through their direct involvement with foreign officials and the income from international trade.
