Dalian is a major city and seaport in the south of Liaoning Province, People's Republic of China. It is the southernmost city of Northeast China and China's northernmost warm water port, at the tip of the Liaodong Peninsula. Dalian is the province's second largest city and has sub-provincial administrative status; only the provincial capital (Shenyang) is larger. The Shandong Peninsula lies southwest across the Bohai Sea; Korea lies across the Yellow Sea to the east.
Today, a financial, shipping and logistics center for Northeast Asia, Dalian has a significant history of being used by foreign powers for its ports: Dalian proper was previously known as both Dalny (Russian: Дальний; Dal'nii) and Dairen (Japanese: 大連) but it was better known as both Port Arthur (Russian: Порт-Артур; Port-Artur) and Ryojun (Japanese: 旅順) from its Lüshunkou district. In 2006, Dalian was named China's most livable city by China Daily.
