South Korea's benchmark Kospi index closed nearly 1 percent higher on Tuesday, driven by broad-based strength in the technology sector.
The rally reflected sustained investor optimism regarding diplomatic efforts to ease geopolitical tensions in the Middle East, specifically the prospect of resumed negotiations between the United States and Iran in Qatar.
Technology stocks were the primary engine of the day's gains, outperforming broader market indices as risk appetite improved.
The positive sentiment in Seoul followed a session of broad gains across Asian equity markets earlier in the week, which had been fueled by reports of progress in peace talks between Washington and Tehran.
The Kospi's advance extended a positive trend that began with modest gains late Tuesday morning, supported by overnight strength on Wall Street.
The market's reaction underscores the sensitivity of Asian equities to geopolitical risk premiums.
