Previously known as Qinzhou, the port of Dalian as it is today has only been in existence since the late 19th century when Russia and Japan fought and alternately had control of the area. Some evidence of Russian and Japanese architectural styles can be seen around Zhongshan Square.

The city government has made concerted attempts to improve the city environment and its clean streets and air have gained international recognition. Dalian nearby beaches and beautiful countryside make it a popular summer resort.
