Despite a plethora of studies on ROK–US relations, few have systematically examined the factors that have caused changes in the relationship between the two states. To fill this gap in the literature, this article investigates the factors that have caused the fluctuation in the relationship between South Korea and the United States in recent years. The authors argue that three factors have affected ROK–US relations in recent decades: (i) domestic politics; (ii) the international factor; and (iii) a series of incidents that contributed to the rise of anti‐US sentiments in South Korea. These changes in the internal and external political environment have altered the relationship between Seoul and Washington and have caused considerable friction between the two countries.

哪些因素影响朝美关系？

尽管对韩美关系进行了大量研究，但很少有人系统地研究了导致两国关系变化的因素。为了填补文献中的空白，本文研究了近年来导致韩美关系出现波动的因素。作者认为，近几十年来，三个因素影响了韩美关系：（i）国内政治；（ii）国际因素；（iii）一系列导致韩国反美情绪上升的事件。内部和外部政治环境的这些变化改变了汉城和华盛顿之间的关系，并在两国之间造成了很大的摩擦。
