On the Change of US Policy Towards China During 1949—1950

1949年底，美国政府从对苏遏制的战略角度出发，基本确立了准备承认新中国和放弃台湾的对华政策。然而，在此关键时期，美国的战略指导思想发生变化，美国国内以“麦卡锡主义”为代表，掀起了反华反共的政治思潮，国内政治环境严重恶化。这使得美国不得不改变艾奇逊现实主义的对华政策。随着朝鲜战争的爆发，美国开始了对新中国的全面封锁与遏制。

Towards the end of 1949,from the strategic perspective of containing the Soviet Union,a policy of preparing to recognize New China and giving up Taiwan was basically established by the Truman Administration.However, at this critical stage,US strategic thinking suddenly became more inflexible and tougher,while the rise of McCarthyism made the domestic political atmosphere in creasingly poisonous,setting off a new antiChina,antiCommunist upsurge.All o f the above made the Truman Administration have to change Acheson's realistic po licy towards China.After the Korean War broke out,US started to make all efforts to isolate and contain China.
