I don't think they are mutually exclusive. Yes they are ahead of their "plan" like their military modernization and infrastructure project like HSR, HVDC power grid, nuke plants all over the country, modernization of the rural area with home appliances, roads, electricity, and internet.
However they are hitting the middle income trap way ahead of their supposed development target. The real estate price is not supposed to be this high when their income is still not there yet. These are problems wealthier nations have AFTER their standard of living is much more well off. Their financial system is not sustainable unless they let go of some more central planning, but they can't, otherwise they will not be able to withstand financial crisis on their own.
Most importantly their currency is still USD backed, so they will be at the mercy of USD just like Japan, S Korea, etc. RMB aren't Euro, AUD, British pound, Swiss Franc.
