青岛市

Qingdao is a prefecture-level city in the eastern Shandong Province of China. Located on China's Yellow Sea coast, Qingdao was long an important fortress. In 1897, the city was ceded to Germany. For the Germans Qingdao (Tsingtau) was a strategic trade center, port and base for its East Asia Squadron, allowing the German navy to project dominance in the Pacific. In 1914, following the outbreak of World War I, Japan occupied the city and the surrounding province during the Siege of Tsingtao. In 1915, China agreed to recognize Japan's special position in the territory through what became known as the Twenty-One Demands. In 1918, the Chinese government, under the control of the warlord Duan Qirui, secretly agreed to Japanese terms in exchange for a loan. Following the First World War, during the Paris Peace Conference, Japan secured agreements with the Allied powers to recognize its claim to the areas in Shandong, which included Qingdao, previously occupied by Germany. In 1922, Shandong reverted to Chinese control following the United States' mediation during the Washington Naval Conference. Today, Qingdao is a major nodal city of the Belt and Road Initiative (BRI) that connects Continental and East Asia with Europe. It has the highest GDP of any city in the province.
