Although inspired by the nineteenth-century term ‘Silk Road(s)’, the phrase ‘Maritime Silk Road’ has its own origins, connotations, and applications. This article examines the emergence of the latter term as a China-centric concept and its various entanglements since the early 1980s, involving the People’s Republic of China’s (PRC) political bodies, academia, the ‘open door’ policy, the pursuit of World Heritage listings, and the current ‘Belt and Road Initiative’. These entanglements, the article contends, have resulted in the emergence of what could be called a ‘Maritime Silk Road’ ecosystem in the PRC. The analysis of this ecosystem presented in the article reveals not only the processes through which a narrative on China’s engagement with the maritime world has been constructed over time, but also its association with issues of national pride, heritage- and tradition-making, foreign-policy objectives, and claims to territorial sovereignty. As such, the ‘Maritime Silk Road’ must be understood as a concept that is intimately entwined with the recent history of the PRC and distinct from its nineteenth-century antecedent, which was used as a label for overland connectivity.
