研究抗战后期美国对中共态度转变的原因,有助于研究战后中美关系演变。也为新中国成立后我国外交上奉行“一边倒”政策的历史原因和研究冷战初期国际政治背景提供了佐证。对于深入研究抗战后期美国对华政策实质和中共与美国关系的发展变化有一定的现实意义,从而有助于加深对当代中美关系的了解和认识。 Studying the reasons why the United States changed its attitude towards the CPC during the post-war period is helpful for studying the evolution of Sino-U.S. Relations after the war. It also provides evidence for the historical reasons for pursuing the “one-sided” policy in our diplomatic efforts after the founding of new China and for studying the international political context in the early Cold War era. It is of practical significance to further study the essence of the U.S. policy towards China and the development and changes of the relations between the CPC and the United States in the latter part of the Anti-Japanese War, which will help to deepen the understanding and understanding of contemporary China-US relations.
