South Korean shares closed a tad higher Wednesday, as investors focused on the recent round of Ukraine-Russia peace talks that ended earlier in the day. The Korean won steeply rose against the US dollar.

The benchmark Korea Composite Stock Price Index advanced 5.67 points, or 0.21 percent, to close at 2,746.74 points.

Institutions bought a net 160 billion won, while foreigners sold 11 billion won and retail investors offloaded 138 billion won.

Stocks came off to a solid start, tracking overnight gains on Wall Street.

The tech-heavy Nasdaq climbed 1.84 percent and the Dow Jones Industrial Average advanced 0.97 percent, as investors pinned hopes on easing geopolitical tensions amid the Ukraine-Russia peace talks.

"The (latest) peace talks between Russia and Ukraine sent positive signals but was not decisive, which limited the stock gains," said Kiwoom Securities analyst Kim Sae-hun.
