Central Huijin Investment Ltd, the domestic arm of China's sovereign wealth-fund, has completed a rescue scheme to increase shareholdings in China's three largest banks, which was set in motion in the wake of the financial crash, according to the lenders.

But the retreat of the major stock rescuer would not likely drag down market sentiment and the market has pulled out of the worst, said analysts.

The Industrial & Commercial Bank of China (ICBC), Bank of China (BOC) and China Construction Bank (CCB) announced the conclusion of Huijin's year-long program over the weekend.
