It'd be pretty weird of Chinese exchanges to continue having these limits for any longer than a couple of weeks.
To a Chinese whale who manipulates the price of one of these exchanges or does high-volume arbitrage trading, a withdrawal limit of 10 BTC is nothing. A million dollars or so in a year is meaningless to some of them.
I'd be very surprised if LocalBitcoins trading was accepted by the Chinese government as well considering the regulations they want to impose on Bitcoin trading.
In my opinion the limits has nothing to do with whales and manipulation, but rather an attempt to "control" a out flow of bitcoins from these
regulated exchanges. A lot of Chinese Bitcoin users has already moved on and would, given the opportunity to do it, move ALL their coins out
of these exchanges. They know this is going to happen and they want to slow it down.
