Algeria is emblematic of the inconspicuous redeployment of merchant supply networks in the East and South of the Mediterranean. Examining the routes from Algerian marketplaces to the Chinese city of Yiwu allows us to better understand their nature and their functioning. This article considers the simultaneous construction of the “Silk Roads” at three levels: transnational between Algeria and China, national in a country where consumer market is increasing, and transregional. The transregional level is an intersection of the two other levels that is organized from the anchor points of globalized trading posts and marketplaces located in East Algeria. Comparing these three levels enables us to shed light on the formation of global networks—which we call routes—that are situated at the crossroads of local, regional, national, and transnational rationales and arise from arrangements at multiple scales among multiple actors. It is now possible to sketch a chronology of the growth in the marketplaces where Algerian importers have obtained supplies for almost forty years, thanks to recent research into the accounts of Algerian traders, collected during continuous and regular surveys conducted by the two authors in Algeria, Dubai, and China, since the early 2000s. These studies identified the places and the construction stages of these transnational routes.
