Eyes are on negotiations with the US on Washington's aggressive tariff scheme, with 10 days to go before the US' country-specific tariffs will resume.

Top chemical firm LG Chem soared 1.44 percent, and No. 1 steelmaker Posco Holdings advanced 1.54 percent.

Nuclear power plant manufacturer Doosan Enerbility spiked 7.6 percent on news that its president, Kim Jung-kwan, was nominated as industry minister.

Carmakers opened mixed. Top automaker Hyundai Motor edged up 0.12 percent, while its sister affiliate Kia shed 0.1 percent.
