Cooperation between Germany and China was instrumental in modernizing the industry and the armed forces of the Republic of China prior to the Second Sino-Japanese War. The Republic of China, which succeeded the Qing Dynasty in 1912, was fraught with factional warlordism and foreign incursions. The Northern Expedition of 1928 nominally unified China under Kuomintang (KMT) control, yet Imperial Japan loomed as the greatest foreign threat. The Chinese urgency for modernizing its military and national defense industry, coupled with Germany's need for a stable supply of raw materials, put the two states on the road of close relations from the late 1920s to the late 1930s. Although intense cooperation lasted only until the start of the war with Japan in 1937, and concrete measures at industrial reform started in earnest only in 1936, it had a profound effect on Chinese modernization and the capability of the Chinese to resist the Japanese in the war.

Shortly after the ROC's establishment in 1912, while it was still located on the Asian mainland, the government used the abbreviation "China" (Zhōngguó) to refer to itself.
