“门户开放政策”提出后贯穿于冷战结束前美国外交的始终,距今已有100多年,已成为国际社会基本接受的原则。冷战结束后,美国外交出现了“新门户开放主义”。①现重点就“门户开放政策”与“新门户开放主义”各自的特点、异同及内在的联系作历史的分析。 Since the “Open Door Policy” was put forward, the U.S. diplomacy that runs through the end of the Cold War has lasted for more than 100 years and has become the basic principle accepted by the international community. After the cold war ended, “U.S. new diplomacy” emerged as a “new open door.” (1) The current focus is on the historical analysis of the respective characteristics, similarities and differences and the inherent links between “the open door policy” and “the new open door”.
