This Saturday, Chinese President Xi Jinping will launch what is being billed as the most important conclave of Chinese leaders since 1978, the year that Deng Xiaoping transformed China from a dying Red giant into a market-driven dynamo. (“Seek truth from facts,” rather than communist ideology, he said.) The historic “Third Plenum” of Xi's term is meant to signal that he has consolidated power, decided on a direction for the country, and achieved consensus with the political class.
