Under the ambitious leadership of President Xi Jinping, China is zealously transforming its wealth and economic power into potent tools of global political influence. But China’s foreign policy initiatives, even the vaunted “Belt and Road,” will be shaped and redefined as they confront the ground realities of local and regional politics outside China. In China’s Western Horizon, Daniel S.

In session four, the author leads the discussion to conclude the series.
