SEOUL, October 21 (AJP) - Major Asian stock markets closed mostly higher on Tuesday amid easing global trade tensions and improved investor sentiment, while South Korea’s benchmark index stood out as the world’s best performer of the month.

In Seoul, the KOSPI closed at a fresh record of 3,814.69, up 1.76 percent from the previous session. The secondary KOSDAQ gained 1.89 percent to close at 875.77. Institutional investors drove the rally with strong buying despite continued foreign selling pressure. Technology stocks led the gains, with SK hynix jumping 4.2 percent to a new high of 485,500 won and Samsung Electronics edging up 0.2 percent to 98,100 won.

Japan’s Nikkei 225 surged 3.12 percent to 49,186, supported by optimism over political stability and anticipated fiscal stimulus. Tech and AI-related shares, including SoftBank, Advantest, and Tokyo Electron, were among the top gainers.

In Taipei, the TAIEX rose 386.26 points, or 1.41 percent, to close at 27,688.63, lifted by semiconductor stocks such as TSMC, which gained 2.07 percent.

Vietnam’s VN-Index also advanced, supported by foreign inflows and resilient domestic investor sentiment despite recent volatility. The index closed near 1,700 points, buoyed by expectations of a market reclassification that could draw greater foreign investment.

The rally across Asian markets underscores a cautiously optimistic tone, driven by easing geopolitical tensions and sustained momentum in the region’s semiconductor and technology sectors.
