Chinese stocks ended mixed Thursday after official data showed China's consumer price index (CPI) in October surging to 4.4 percent year on year, a 25-month high.

The benchmark Shanghai Composite Index rose 1.04 percent, or 32.39 points, to close at 3,147.74.

The Shenzhen Component Index lost 0.15 percent, or 20.74 points, to end at 13,684.94.

Combined turnover rose to 506.18 billion yuan (76.41 billion U.S. dollars) from 445.76 billion yuan the previous trading day.

Losers outnumbered gainers 649 to 225 in Shanghai and 806 to 279 in Shenzhen.

China's central bank said Wednesday evening it would raise the deposit reserve requirement for financial institutions by 50 basis points, in an effort to tighten liquidity amid increased inflationary pressures.

Market participants had expected the October CPI to be about 4 percent.

Despite the higher than expected CPI reading, the benchmark Shanghai Composite Index rose, fueled by sharp rises in the shares of oil heavyweights PetroChina and Sinopec.

PetroChina gained 7.69 percent to finish at 12.74 yuan per share while Sinopec rose 5.21 percent to end at 9.49 yuan.
