South Korean stocks opened higher Wednesday as China's central bank announced Tuesday it may add more liquidity to the market amid worries that the economy there is slowing down, analysts said.

The benchmark Korea Composite Stock Price Index (KOSPI) added 10.58 points, or 0.59 percent, to 1,791.21 in the first 15 minutes of trading.

Tech blue chips gathered ground, with LG Electronics rising 2.3 percent and top chipmaker SK hynix adding 2.03 percent. Top flat panel maker LG Dispay gained 1.93 percent.

Carmakers also traded bullish, with No. 1 player Hyundai Motor adding 1.46 percent and its smaller affiliate Kia Motors climbing 1.55 percent. Leading auto parts maker Hyundai Mobis moved up 1.17 percent.

The local currency was trading at 1,154.75 won against the U.S. dollar as of 9:15 a.m., up 5.45 won from Tuesday's close. (Yonhap News)
