1. The contributors to this Special Issue are concerned by the nature of transregional Asian interactions taking place in the field of commerce. They explore this concern through an examination of the experiences, activities, and histories of commodity traders whose life trajectories criss-cross Asia. The articles share a common geographic point of reference: Yiwu - an officially designated ‘international trade city’ located in China’s eastern Zhejiang province. The introduction to the Special Issue analytically locates the individual papers in relationship to a long-standing body of work in anthropology and history on port cities and trading nodes. In so doing it suggests the importance of considering multiple historical processes to understanding Yiwu and its position in China and the world today, as well as, more generally, for the anthropology of ‘globalisation from below’. 2. This article explores the nature of inter-Asian trade dynamics through a consideration of the role played by traders from northern Afghanistan’s Central Asian borderlands. It explores the role that traders from this region have played in commercial exchanges involving China, the Arabian Peninsula and a range of settings in West Asia. In addition to documenting the inter-Asian scope of these traders’ activities, the article also addresses the shifting nature of their identity formations in relationship to successive waves of migration. The traders often identify themselves in relationship to ethno-national identity categories (Turkmen, Uzbek and Tajik) that are politically salient in Central Asia and Afghanistan today. At the same time, the traders also emphasise their being from families that migrated from the territories of the Emirate of Bukhara during the early years of communist rule in the 1920s and 1930s. In the context of the Soviet invasion of Afghanistan in 1979, many of these families moved from Afghanistan to Saudi Arabia, often staying for several years in cities and towns in Pakistan. Over the past three decades, Central Asian émigré families have increasingly established their businesses and communities in the Arabian Peninsula and Turkey; they also run offices in the trading cities of maritime China.
