中共与蒋介石集团的斗争贯穿于整个抗战时期 ,体现在抗日统一战线内部。蒋介石集团兼有抗日与反共两面性 ,他们既把中共当作抗日同盟者 ,又把中共看成是真正的敌人。他们始终坚持反共 ,不断制造反共磨擦 ,发动了三次反共高潮。面对抗日统一战线内异常复杂的斗争 ,以毛泽东为核心的中共中央既反右又反“左” ,在总结历史经验的基础上 ,在斗争实践中形成和完善了一整套斗争策略原则。由于中共高超的斗争策略 ,迫使蒋介石集团一直留在了抗日阵营 ,巩固和扩大了抗日统一战线 The CCP’s struggle with the Chiang Kai-shek clique runs through the entire period of the Anti-Japanese War and is reflected in the anti-Japanese united front. The Chiang Kai-shek clique has both anti-Japanese and anti-communist sides. They regard the CCP as both an anti-Japanese alliance and a CCP as their true enemy. They have always insisted on opposing communism and constantly creating friction with the communists to launch three anti-communal climaxes. In the face of the extremely complicated struggle in the anti-Japanese united front, the CPC Central Committee with Mao Zedong as the core has both anti-right and anti “leftist” principles. On the basis of summing up historical experiences, it has formed and perfected a set of principles and tactics in the struggle. Because of the superior tactics of the CCP, it forced the Chiang Kai-shek clique to stay in the anti-Japanese camp and consolidate and expand the anti-Japanese united front
