Korean stocks opened slightly lower Tuesday, tracking overnight losses on Wall Street as a decline in U.S. tech firms outweighed optimism over progress in peace talks between the United States and Iran.
The benchmark Korea Composite Stock Price Index (KOSPI) lost 31.01 points, or 0.34 percent, at 9,083.54 at the opening bell.
Overnight, U.S. Vice President JD Vance said a "very good foundation" had been established for negotiations toward a final agreement with Iran, while mediators also reported progress in the talks.
However, U.S. stocks closed mixed, with the tech-heavy Nasdaq declining 1.3 percent amid concerns about major technology companies.
