This article traces ROK–US negotiations for the termination of the ROK's nuclear weapons program. It was not solely an issue of ROK–US relations; France and Canada, other allies of the United States, were also involved in the ROK's nuclear weapons development. When an ally (ROK) attempted to develop nuclear weapons and another ally (France) pursued commercial interests by exporting nuclear technology, the US-led non-proliferation regime was put at risk. Therefore, the US had to coordinate the interests of its allies. In particular, it attempted to dissuade France from exporting nuclear technology with the support of another ally (Canada). By examining how the US endeavored to coordinate diverse interests, this study ultimately demonstrates that one of the prerequisites for establishing a successful non-proliferation regime led by the US was how to dissuade its ally from seeking financial gain through the export of nuclear technology and instead persuade them to support US-led non-proliferation regime building.

本文追溯了韩美终止韩国核武器计划的谈判。这不仅仅是韩美关系的问题，也是韩美关系的问题。美国的其他盟友法国和加拿大也参与了韩国的核武器开发。当一个盟友（韩国）试图发展核武器，另一个盟友（法国）通过出口核技术追求商业利益时，美国领导的防扩散体系面临风险。因此，美国必须协调盟友的利益。特别是，它试图在另一个盟友（加拿大）的支持下阻止法国出口核技术。本研究通过考察美国如何努力协调不同利益，最终表明，美国主导的防扩散体系成功建立的前提之一是如何劝阻其盟友通过核技术出口谋取经济利益，而说服他们支持美国主导的防扩散体系建设。
