Adolf Hitler had allowed Han Chinese and Japanese soldiers to study in Nazi German military academies and serve in the Nazi German Wehrmacht as part of their combat training. Since 1926, Germany had supported the Republic of China militarily and industrially. Germany had also sent advisers such as Alexander von Falkenhausen and Hans von Seeckt to assist the Chinese, most notably in the Chinese Civil War and China's anti-communist campaigns. Max Bauer was sent to China and served as one of Chiang Kai-shek's advisers. Around this time, Hsiang-hsi Kung, the Republic of China Minister of Finance, visited Nazi Germany and was warmly welcomed by Adolf Hitler on June 13, 1937. During this meeting, Adolf Hitler, Hermann Göring and Hjalmar Schacht bestowed upon Hsiang-hsi Kung an honorary doctorate degree, and attempted to open China's market to German exports. And in order to attract more Han Chinese students to study in Germany, Adolf Hitler, Hermann Göring and Hjalmar Schacht earmarked for 100,000 reichsmarks for Han Chinese students studying in the universities and military academies of Nazi Germany after they persuaded a German industrialist to set aside the money for that purpose. Additionally, Hsiang-hsi Kung, in favor of commercial credits, politely refused a generous international loan offer by Adolf Hitler. The most famous of these Han Chinese Nazi soldiers was Chiang Wei-kuo, the son of Republic of China President Chiang Kai-shek, who studied military strategy and tactics at a Nazi German Kriegsschule in Munich, and subsequently achieved the rank of lieutenant and served as a soldier in the Wehrmacht on active combat duty in Europe until his return to the Republic of China during the later years of World War II.
