‘Labor Activists and the New Working Class in China’ is an ethnographic work examining an export jewelry industrial district in Pearl River Delta of China. While well known that China is undergoing an unprecedented capitalist transformation, few have noted the new working class of China are also actively striving to alter their fate through labor struggles. Parry Leung lived for twelve months in the migrant worker dwelling sites, and kept close contact with the strike activists. Leung illuminates how strikes emerge and transform in an authoritarian state, by enhancing our understanding on the informal agency power of strike organizers in labor activism.
