South Korea's benchmark KOSPI rebounded to the 5,500 level just a day after a sharp selloff, as investor sentiment improved following Trump's remarks as well as a drop in global oil prices from over US$100 per barrel to around $80.
Even a buy-side sidecar kicked in during the early trading session, as the KOSPI rose 6.13 percent to 5,573.55 and the tech-heavy KOSDAQ gained 4.11 percent to 1,147.63 just a few hours after the day's trading began.
Foreign and institutional investors led the buying, with net purchases of 1.07 trillion won and 510 billion won, respectively, while individual investors sold a net 1.47 trillion won.
Japanese shares also rebounded after a steep selloff the previous day, when the Nikkei 225 recorded its third-largest intraday drop on record.
Tokyo's index rose 2.95 percent to 54,287.95 by 10:00 a.m., recovering some of the prior session's losses as falling oil prices and optimism over a possible settlement in the Middle East boosted investor sentiment. Chip-related stocks drove the gains, with Tokyo Electron rising 3.49 percent to 40,280 yen ($268) and Advantest climbing 5.51 percent to 24,135 yen.
Taiwanese shares also moved higher, with the TAIEX rising 3.14 percent to 33,118.03 shortly after trading began in Taipei. In Hong Kong, the Hang Seng Index advanced 1.31 percent to 25,740.29.
Meanwhile, overnight gains in memory chip stocks on Wall Street lifted Korean semiconductor shares. SanDisk surged 11.64 percent, while Lam Research and Micron Technology rose 5.93 percent and 5.14 percent, respectively. In Seoul, Samsung Electronics gained 9.68 percent to 190,300 won, and SK hynix jumped 11.36 percent to 931,000 won.
However, defense and refinery stocks, which had jumped amid geopolitical tensions, retreated after Trump's comments. S-Oil fell 7.51 percent to 118,900 won, and Hanwha Systems dropped 3.63 percent to 156,800 won. Other defense-related stocks also declined, with LIG Nex1 falling 2.51 percent to 776,000 won and Hyundai Rotem slipping 1.16 percent to 213,000 won.
Hanwha Aerospace rebounded 2.86 percent to 1,476,000 won after early losses, reflecting a growing divergence among defense stocks as investors increasingly differentiate based on company fundamentals and order momentum.
Shares of automakers climbed, as Hyundai Motor added 5.72 percent to 536,000 won and Kia rose 4.76 percent to 160,700 won. Among other heavyweights, Samsung Biologics rose 2.09 percent to 1,612,000 won, LG Energy Solution added 2.78 percent to 369,500 won, and Samsung C&T climbed 3.51 percent to 280,000 won.
The won strengthened sharply amid easing oil prices and expectations of an early end to the Middle East conflict, trading around 1,472.70 against the greenback, compared with about 1,494.7 won the previous day.
