No one could have imagined that Shang Lin, Guang Xi, this borderland of South China would become a gold rush for the transnational capital of the overseas Chinese in the 1930s during the "Great Depression" of the world economy, a fertile scientific ground for modern geologists' geological exploration and field research, and an outpost of nation-states aspiring to mining modernity. In the contemporary global encounter between China and Africa, "gold-digging Africa" is like a tropical storm sweeping from the African continent, attracting local grassroots capital and transnational miners to move nimbly around the gold belt of West Africa. These bottom-up flows not only shape a unique world of "wild gold" production but also constitute a restless, hopeful undercurrent of grassroots globalization. This talk will share with you the travels of "wild gold" in the "South" (South China and the Global South), and how this undercurrent of grassroots globalization has violently shaken the local wealth and moral codes.
