British Weihaiwei or Wei-hai-wei, on the northeastern coast of China, was a leased territory of the United Kingdom from 1898 until 1930. The capital was Port Edward, which lay in what is now the centre of Huancui District in the city of Weihai in the province of Shandong. The leased territory covered 288 square miles (750 km2) and included the walled city of Weihaiwei, Port Edward just to the north, Weihaiwei Bay, Liu-kung Island and a mainland area of 72 miles (116 km) of coastline running to a depth of 10 miles (16 km) inland, an area roughly coterminous with the Huancui District of modern Weihai City. Together with Lüshunkou (Port Arthur) it controlled the entrance to the Bohai Sea and, thus, the seaward approaches to Beijing.
