SEOUL, May 16 (Yonhap) -- South Korean stocks sank 1.2 percent Thursday on the escalating trade war between the United States and China, with Washington vowing to ban foreign telecom equipment, analysts said. The Korean won again lost ground against the U.S. dollar.
The benchmark Korea Composite Stock Price Index (KOSPI) plunged 25.09 points, or 1.2 percent, to close at 2,067.69. Trading volume was moderate at 733 million shares worth 5.96 trillion won (US$5 billion), with losers outpacing gainers 542 to 297.
U.S. President Donald Trump signed an executive order that centers on banning the use of foreign telecommunications devices, citing national security, apparently targeting Chinese brands such as Huawei.
"The tension is escalating between Washington and Beijing after Trump announced the order aimed at protecting U.S. telecommunication technology and services," said Yoon Jung-sun, a researcher at KB Securities Co.
Seoul shares started nearly flat over reports that Trump will delay his decision on imposing higher auto tariffs on imported cars and that there could be an exemption for South Korea from the penalties.
But the market went south in the afternoon session on expanded sell-offs by foreign investors.
Foreigners went on a selling spree with a net 467 billion won sold, while institutions dumped a net 37 billion won. Retail investors scooped up 409 billion won net.
Market kingpin Samsung Electronics dipped 2.35 percent to 41,550 won, and No. 2 chipmaker SK hynix lost 3.49 percent to close at 71,900 won. Major electronics firm LG Electronics moved down 2.07 percent to 71,000 won.
Samsung BioLogics dropped 3.39 percent to 299,500 won after prosecutors raided a task force office of Samsung Electronics as part of an investigation into allegations that Samsung Group may have been involved in accounting fraud by its biopharmaceutical unit.
