This article explores the history of the Qingxi Ironworks in late Qing Guizhou. Instead of focusing on state-centered industrialization or technology transfer and scientific knowledge in Qing mining and coal enterprises, this study focuses on the individual ambitions and identity construction of two returned diplomats—Chen Jitong and Chen Mingyuan—who sought to claim authority over a mining interest in China’s southwest interior. By leveraging their knowledge of the West to serve as intermediaries between state and foreign commercial interests, these cosmopolitan yet marginalized elites sought to convert their foreign expertise and avowed commitment to “self-strengthening” into new forms of social and political capital. An examination of the personal networks and written accounts surrounding their entrepreneurial ventures sheds light on the opportunities and challenges experienced by a generation of “foreign affairs” experts in repositioning themselves within the transforming Qing polity through participation in industrialization projects.
