Despite a reputation for abstruse thought, the French intellectual Michel Foucault once explained his research in a straightforward manner: “I set out from a problem expressed in the terms current today and I try to work out its genealogy. Genealogy means that I begin my analysis from a question posed in the present.” Keyu Jin took that approach to heart in The New China Playbook, a work that explains China’s present by tracing its economic genealogy since 1978.
