German-Chinese cooperation in the military and industrial sectors between the two World Wars is closely tied to the German military mission in China from 1927 to 1938. Economic and political conditions in Germany and China during the interwar period brought these two countries closer together. The German military mission laid the groundwork for collaboration between the two states, both of which benefited from it. The German military mission lasted for approximately a decade, during which it had several leaders. It's important to emphasize that despite its military nature, it didn't exclusively focus on military matters. It dealt with military, industrial, economic, and diplomatic issues in the relationship between the two countries. The mission began with Max Bauer, who established initial contacts and gathered interested German officers. Due to Bauer's death, he briefly headed the mission but made a promising start. His successors Hermann Kriebel and Georg Wetzell didn't make a good impression due to their lack of understanding of Chinese political conditions, and during their tenure, the German mission faced a crisis. Relations between the Chinese and German officers deteriorated to the point that Chiang Kai-shek nearly terminated the cooperation. In 1934, Hans von Seeckt became the chief advisor. He managed to mend the strained relations and gave the mission a new impetus. The terms of von Seeckt and his successor Alexander von Falkenhausen marked the peak of the German mission's achievements. Von Falkenhausen took over the mission's leadership in 1935 and became its final head. The German military mission concluded in 1938 with the outbreak of the Second Sino-Japanese War. Hitler, in solidarity with his new ally Japan, withdrew German officers at that time.
