This essay introduces the book's core themes, specifically the importance of media, transnational politics, and political imagining in black leftist radicals' efforts to articulate and build solidarity with the socialist project being shaped in China and other communist Asian countries. The chapter begins by theorizing and interrogating "radical imagining," the book's central analytic, emphasizing the empowering and liberating power of media and cultural production within such transnational political imagining and activism, as well as its disjunctive and problematic contours. The chapter then moves to position the book in conversation with several bodies of literature, most centrally scholarship concerned with Chinese political communication with foreign groups, twentieth century black leftist internationalism, and works that challenge previous scholarship’s masculinist framing of Cold War black radical intellectualism.
