Seoul shares retreat on China, U.S. caution

SEOUL, March 4 (Reuters) - Seoul shares turned lower on Thursday, pressured by losses in key technology issues such as Samsung Electronics (005930.KS) and securities firms such as Woori Investment (005940.KS).

Analysts said caution pervaded ahead of U.S. job data and the annual session of China's National People's Congress, which is scheduled on Friday.

The Korea Composite Stock Price Index .KS11 (KOSPI) finished down 0.26 percent at 1,618.20 points, snapping a three-session gaining streak.
