Shanghai

Shanghai is China's largest city and its primary commercial and financial hub, with a population of around 29 million in its administrative area. It sits at the mouth of the Yangtze River on the East China coast and is home to the world's busiest container port, handling around 47 million twenty-foot equivalent units per year. The city hosts the Shanghai Stock Exchange and the headquarters of hundreds of Chinese state-owned enterprises and multinational corporations.

Shanghai was forcibly opened to foreign trade by the Treaty of Nanking in 1842 and grew rapidly as an international settlement through the late 19th and early 20th centuries. After 1949 it became a centre of Chinese industrial production. Since Deng Xiaoping designated Pudong a special economic zone in 1990, Shanghai has grown into a global financial centre, with the Lujiazui skyline among the most recognisable in the world. It remains under the direct jurisdiction of the central Chinese government rather than a province.

In 2026 Shanghai-based shipping operator Shanghai Xuanrun Shipping was sanctioned by the United States for its role in carrying Iranian crude through the Strait of Hormuz during the blockade. The firm's vessels were among the sanctioned Chinese tankers tracked transiting Hormuz after the CENTCOM blockade began .
