After the Second World War, the US government established a new oil order, forming close ties with three major oil companies—Standard Vacuum, Shell, and California-Texas—referred to as the ‘Three Sisters’ in Korea, which was newly liberated from Japanese colonialism. Even after the South Korean government was established, the US government and the Three Sisters worked to maintain the order. Using the carrot of the Economic Cooperation Administration (ECA) funds, in 1949 the US government pressured the South Korean government into oil agreements that would facilitate the supply of petroleum products to the country. The 1949 oil agreements were completed after three rounds of negotiations. The process of signing the agreements was not limited to the import, storage, and sale of petroleum products in exchange for US aid to South Korea. It also sought to respond to the various interests of Koreans who wanted to create an independent economic structure in the midst of establishing a new government. This article explores the three rounds of negotiations for the 1949 oil agreements whereby the symbiotic relationship between the US government and the Three Sisters was realized in partnership with the interests of the South Korean government. Furthermore, it seeks to broaden the research on the history of Korean oil by promoting an understanding of how US oil policy affected Korea immediately after its liberation from Japanese colonial rule.

第二次世界大战后，美国政府建立了新的石油秩序，与标准真空公司、壳牌公司和加州德克萨斯公司这三大石油公司建立了密切的联系，在刚从朝鲜半岛解放出来的韩国被称为“三姐妹”。日本殖民主义。即使韩国政府成立后，美国政府和三姐妹仍在努力维持秩序。1949 年，美国政府利用经济合作管理局 (ECA) 资金的胡萝卜，向韩国政府施压，签订石油协议，以促进向该国供应石油产品。1949年石油协议经过三轮谈判才达成。签署协议的过程不仅限于进口、储存和销售石油产品以换取美国对韩国的援助。它还试图回应韩国人希望在建立新政府的过程中建立独立经济结构的各种利益。本文探讨了 1949 年石油协议的三轮谈判，其中美国政府与三姐妹国家之间的共生关系是与韩国政府的利益合作实现的。此外，它还试图通过促进人们对韩国从日本殖民统治解放后美国石油政策如何影响韩国的理解来扩大对韩国石油历史的研究。
