SHANGHAI, Dec 22 (Reuters) - China's main stock indexes barely moved on Thursday, as strength in shares of state-owned enterprises (SOE) was offset by persisting tight liquidity in the wake of a bond scandal.
The CSI300 index, which rose nearly 1 percent on Wednesday, fell 0.1 percent, to 3,335.81 points, while the Shanghai Composite Index lost 0.1 percent, to 3,140.15 points.
After problems with forged bonds emerged, China's central bank has asked its branches to look into entrusted bond holding agreements between some commercial banks and non-financial firms.

The Shanghai SOEs Index was up more than 0.6 percent at the close, bucking a broad downward trend.
