Green silk roads, partner state development, and environmental governance: Belt and road infrastructure on the Sino-East African frontier

China's Belt and Road Initiative (BRI) is reorienting global development. Few scholars, however, query relationships between green silk road discourse, BRI infrastructure, partner state development goals, and environmental governance. This article details the roots of green silk road discourse in efforts to environmentally engineer China's desert landscapes. Much like large-scale nature-based infrastructure projects in China, BRI infrastructure projects abroad precipitate a range of socioeconomic and environmental outcomes. Through juxtaposing terrestrial infrastructure development in Ethiopia with maritime infrastructure development in Djibouti, the article demonstrates how different types of BRI infrastructure projects shape environmental governance and advance the development agendas of partner countries. Sugar plantations, roads, railways, and energy infrastructure in Ethiopia further Ethiopian state development plans while transforming Indigenous people's relations to their land and livelihoods. In Djibouti, port infrastructure and military bases figure centrally in strategic rentiership for the Djiboutian state with ancillary effects on fisheries and international trade. The article illustrates how relative articulations between East African central government development interests, environmental governance, and infrastructure are mediated by varieties of Chinese capital. The comparative analysis disrupts simplistic narratives of "win-win" partnerships and "China as threat" to partner state autonomy.
