| By the incident of Tang shan in1931, the cooperation between Wang Jingwei and Hu Hanmin formulated as to anti-Chiang, leading to confrontation between Nanjing and Guangdong. With political climate change enormously after September Eighteenth Incident, the cooperation between Wang and Hu went into dilemma, however the relationship between Chiang and Wang improved gradually. After Sun Ke cabinet was overthrew by Chiang and Wang together, Chiang and Wang official began to cooperate in the form of Chiang dominating military force, Wang leading government,and the KMT controlled jointly by Chiang and Wang. That cooperation got preliminary consolidation in the process of dealing with Battle of Shanghai. Duo to collision between Wang Jingwei and Zhang Xueliang in August1932, the stability of political situation was undermined. Failing to maintain the status quo, Chiang had to choose Zhang and protected his power over North China. As a result, Wang went abroad for medical treatment angrily, seriously frustrating the cooperation. The situation that Japanese troops occupied Re he province and continued to attack North China made Chiang alter previous measures. The cooperation recovered after Chiang took measures to show concession to Wang at the cost of dismissing Zhang. After Wang resumed administrative power in1933, not only was mutual political trust between Chiang and Wang consolidated, but that consensus in political idea enlarged, which provided a basis to a series of improvements over the cooperation. Owing to those improvements, not only did the Lushan model take shape, but their power relation reached relative balance, which Gu case in1934reflected typically. It made continuously negative impact on the cooperation that sustaining anti-Wang movement within KMT and a variety of drawbacks of the political mechanism. The resignation of Wang Jingwei in1935had a directly logic connection with those factors. Although there were some detrimental effects on the cooperation inevitably, the cooperation basis still maintained during the period of the fifth national congress of KMT. The Xi’an Incident in1936, which was the one of those turning point in the evolving process of the relationship between Chiang and Wang, plant a seed of the cooperation rupture. Consequently, the relationship between Chiang and Wang sustained to deteriorate and went into complete rupture irreversibly. |
