Pretty late to the discussion here, but a somewhat popular theme on Chinese Twitter regarding the current affairs, closure of the US CG, and the concept 经济内循环/内部大循环 the internal economic cycle/main domestic cycle is a sign that China will revert to the closed state (i.e. prior to reforming & opening up) and maybe also bring back planned economy in a few years as the country gets more and more alienated by the rest of the world (in order to conserve FX reserves and to ensure the survival of the Party). To me the idea seems quite unlikely, but I'm no China expert. Does this scenario sound plausible to you?
