After winning Dalian as the result of the Russo-Japanese War of 1904-05, Japan continued to build the Russian-built city with the modern buildings on "Large Square". With the conquest and establishment of the puppet state Manchukuo, massive funds and efforts were invested into the master plan for the construction of the capital city of Shinkyō (Hsinking). Many official buildings erected during the colonial period still stand today, including those of the Eight Grand Ministries of Manchukuo, the Imperial Palace, the headquarters of the Kwantung Army and Datong Avenue.
