Seoul shares fell in early domestic trade Wednesday, touching a near-three week low as persisting worries about China's economic growth outlook cut appetites for riskier assets. The Korea Composite Stock Price Index (KOSPI) was down 1.2 percent at 1,939.86 points as of 0215 GMT. The index earlier traded as low as 1,938.60, its weakest level since Feb. 20. A sharper-than-expected slowdown in China would likely hurt earnings of major local manufacturers, as the world's second-largest economy is South Korea's biggest exports market. "Investors have yet to shake their concerns about corporate debt default and shadow banking" in China, said E-Trade Investment analyst Choi Kwang-hyeok.
