Passage: During this period, Germany did not actively pursue imperialist ambitions in China, and appeared relatively restrained compared to the United Kingdom and France. Thus, the Chinese government saw Germany as a partner in helping China in its modernisation. In the 1880s, the German shipyard AG Vulcan Stettin built two of the most modern and powerful warships of its day—the pre-dreadnought battleships Zhenyuan and Dingyuan—for the Chinese Beiyang Fleet that saw considerable action during the First Sino-Japanese War. After China's first modernization efforts apparently failed following its defeat in the First Sino-Japanese War, Yuan Shi-kai requested German help in creating the Self-Strengthening Army (Chinese: 自強軍; pinyin: Zìqiáng Jūn) and the Newly Created Army (新建陸軍; Xīnjìan Lùjūn). German assistance not only concerned military, but also industrial and technical matters. For example, in the late 1880s, the Chinese government made a contract with the German company Krupp to build a series of fortifications around Port Arthur.
