I must say in the last 2-3 years I have come to admire the Chinese financial authoriries, despite all the noise about their controls.... a new order of "controlled capitalism"?? Pumped billions to lift the economy in 2009, started pro-actively hiking rates and controlling property market in the last 2 years to check inflation, now I saw they're using their offshore banks to encourage other institutions to maintain RMB deposits/reserves ->probably targeting RMB as a reserve ccy in the near future, as trades with China become unavoidable.
CBK is really caught between a rock and a hard place. They may have to resort to some form of exchange controls, similar to the ones in the 90's, on large tickets, as they run out of reserve ammunitions.
