In this episode, the focus is on remarks by a senior Chinese America watcher, Prof. Jia Qingguo. Though a longtime supporter of US-China engagement, Jia reports on mounting Chinese concern about US policy on Taiwan and changing Chinese perspectives on nuclear weapons as well. Jia's comments bode ill for the immediate future.
