I wonder why btcchina and okcoin cny are low ( arround 7200 cny / 1050 usd ). If these markets dont go up I think other markets cant go up to 1300.
It does not matter if there are price difference that exist in various locations.
When the price decides to move up, for example, those other exchanges (even in china) will likely move up too - whether the arbitrage spread continues to be in the 10% to 15% territory or if it becomes a different amount is another story. These situations are not locked in, and one part of the world does not control bitcoin prices, even if there can exist some causes and effects and some price pressures in one direction or another because of those kinds of dynamics that you mention.
