[SEOUL] South Korean shares edged up in mixed trading on Tuesday, as broad risk aversion eased and investors adopted a wait-and-see posture ahead of the US Federal Reserve's rate-setting meeting starting later in the global day.

The Korea Composite Stock Price Index (Kospi) rose 0.3 per cent to close at 1,932.97 points.

Foreigners were net sellers for a 10th straight day, dumping a net 352.1 billion won (S$419.47 million) of shares on the main board, preliminary data showed.

Meanwhile, the South Korean won ended local trade up 0.1 per cent at 1,183.4 per dollar on offshore selling of the greenback ahead of the Fed's decision.
