Currency control is a double edge sword. If it can help the economy in bad times, the Japs would hv adopted it. The cons of currency control will out weight the pros when China badly needed external trades to help its economy.    Now that China is fighting against using us dollars.  Capital controls in China will only b a stumbling block.  China might even take longer time than necessary to recover.

Indonesia, Brazil, India Europe and US block China exports with tariffs ...this closes China last path out of its current economic problems.

De-dollarisation is a red herring that cannot work with so many BRICs nation owning debts in USD that needs to be repaid...they will need more USD now as interest rate is high.
