This study examines how the post-Cold War geopolitical context penetrated through the struggles and empowerment of North Korean female defector entrepreneurs in South Korea. Reconceptualizing the notion of intersectionality, the study focuses on a grey area of informality and the resilience of these women. Based on in-depth interviews and participant observations, the findings indicate that these women leveraged geopolitical limits to develop their entrepreneurial assets. informality developed through their involvement in Jangmadang and cross-border mobilities via informal brokerage. Through human-trafficked marriages, they stayed in China, learning the Chinese language and working in South Korean companies. The disadvantages of the job market and gender roles motivated them to start their businesses. The research emphasizes the complex ways in which agency, mobility, and geopolitics intersect.
