How to hedge against specific asset classes at low cost
The essence of hedging is to find an investment that performs well under the conditions that you're concerned about. If you're concerned about China stock dropping, then find something that goes up in value if that asset class goes down.  Maybe put options on a Chinese index fund, or selling short one of those funds? Or, if you're already "in the money" on your Chinese stock position, set a stop loss: instruct your broker to sell if that stock hits X or lower.  That way you keep some gains or limit your losses.  That involves liquidating your position, but if you've had a nice run-up, it may be time to consider selling if you feel that the prospects are dimming.
