Commercial use of wildlife is booming. However, knowledge of trade, price structure and benefit distribution mechanisms remain limited for many endemic, threatened and economically valuable species, impeding efforts to develop conservation intervention schemes in line with sustainable objectives. We illustrate the nature of commercialization of the caterpillar fungus Ophiocordyceps sinensis, collected in a high-altitude Tibetan region. Using the value-chain approach, we document how caterpillar fungus is collected in a remote mountainous region and traded across a wide range of middlemen until it finally reaches high-end markets in urban centres. Mapping the caterpillar fungus value chain helps identify the actors involved and the social institutions (i.e. the rules, norms and arrangements that shape people's behaviours) facilitating access to markets and influencing profit distribution and price structure. We present the complex dynamics of this commercialization process, providing a holistic value-chain analysis that encompasses actors, profits and institutions.

The authors report on new discoveries from Sanxingdui in south-west China. The multidisciplinary approach used at Sanxingdui has enriched the theory and methodology of field archaeology and sets a precedent for future scientific excavations.

An Eastern Han stele with an unusual relief decoration and 367 character memorial inscription tells us much about the south-west of China in early imperial times. Unearthed in 2004 from the banks of the Yangtze River and dated to 173 ce, the stele was dedicated to Quren county magistrate Jing Yun who died 70 years earlier in 103 ce. The paper provides a full translation, annotation, and analysis of the stele's commemorative text, which borrows from the content and language of one of China's oldest anthologies of poems, the Chuci, and places it in its historical context. It also examines the iconography at the head of the stele which reflects beliefs in transcendence and the pursuit of immortality prevalent at the time and demonstrates its close relation to the inscription. Overall, the paper suggests that the decoration and text together exhibit a regional heritage that is distinct to the south-west, its memorial culture, and poetic and religious traditions.

Millions of China's ethnic minority citizens remain subject to competing legal standards, even as state officials strive to strengthen a unified notion of state law. Minority customary law continues to bind many minority citizens in both civil and criminal arenas and often conflicts directly with state law. What happens when these laws conflict? Based on fieldwork in Yunnan, this article shows how local officials and communities navigate legal pluralism and what legal and policy provisions guide them. Granting local judges discretionary authority to set aside state law in favour of customary law, although seemingly undermining law enforcement, may in the long run be the best path to strengthening rule of law in China's minority regions.
