Since the opening of the Sino-Burmese border trade in 1988, the movement of goods and people from both sides has increased rapidly. In 2011, China became Burma's largest trading partner and over half the total volume of goods was accrued in cross-border trade via Yunnan. However, national figures on import-export volumes are derived solely from legal flows, while contraband is largely overlooked. To date, academic studies on contraband have remained insufficient, partly due to the difficulty accessing Burmese border areas, and partly due to the mere challenges in obtaining information about smuggling from those who engage in such activity. This paper, based on multiple fieldwork sites over several years, examines a particular contraband – the smuggling of Chinese motorcycles to Burma on the ‘new’ Burma Road. This shadow economy thrived between 2000 and 2014. While highlighting its economic rationality beyond state control, I attempt to make diachronic and synchronic comparisons by engaging with dialogues within the historical trading mechanism of the mule convoys in the region and also with theories of shadow economies generated from contemporary case studies in other parts of the world. I argue that the formation of this shadow economy is not haphazard but adheres to the ethos of the mule caravan trade, predicated on local knowledge and social networks.
