Passage: After the death of Yuan Shi-kai, the Beiyang government collapsed and the country fell into civil war, with various warlords vying for supremacy. German arms producers began looking to reestablish commercial links with China to tap into its vast market for weapons and military assistance.The Kuomintang government also sought German assistance, and the German-educated Chu Chia-hua (朱家驊; Zhū Jiāhuá) arranged almost all Sino-German contact from 1926 to 1944. There were several reasons other than Germany's technological expertise that made it the top candidate in Chinese foreign relations. First, Germany had no more imperialistic interest in China after World War I. Second, unlike the Soviet Union, which helped with Kuomintang reorganization and opened party membership to communists, Germany had no political interest in China that could lead to confrontations with the central government. Moreover, Chiang Kai-shek saw German unification as something that China could learn and emulate. Thus, Germany was seen as a primary force in the "international development" of China.In 1926, Chu Chia-hua invited Max Bauer to survey investment possibilities in China and the next year Bauer arrived in Guangzhou and was offered a post as Chiang Kai-shek's advisor. Soon, he managed to recruit 46 other German officers to advise and train nationalist forces, while he devised the strategy that allowed the Nationalists to win its 1929 campaigns against the warlords. In 1928, Bauer returned to Germany to recruit a permanent advisory mission for China industrialisation efforts. However, Bauer was not entirely successful as many firms hesitated because of China's political instability, and because Bauer was persona non grata for his participation in the 1920 Kapp Putsch. In addition, Germany was still constrained by the Treaty of Versailles, which made direct military investment impossible. Max Bauer contracted smallpox after his return to China, died and was buried in Shanghai. Bauer's provided the foundation for later Sino-German...
