Tuesday witnessed a mixed performance across Asia-Pacific markets as investors grappled with renewed uncertainties concerning U.S.-Iran peace discussions. Meanwhile, Wall Street’s key indexes reached new peaks, driven by positive sentiment in the tech sector.

Japan’s Nikkei 225 closed with a 0.3% dip, settling at 66,734.24 points, and the Topix index saw a 0.42% decline, finishing at 3,924.24. South Korea’s Kospi index dropped by 0.15% to end at 8,801.49, while the smaller Kosdaq index plunged 2.29% to 1,026.03.

In contrast, Australia’s S&P/ASX 200 maintained its position, closing unchanged at 8,724.4.

Hong Kong’s Hang Seng index surged, showing a 2.41% increase in its final trading hour. Meanwhile, in mainland China, the CSI 300 index climbed by 1.45%, closing at 4,914.56.

India’s Nifty 50 was last up 0.5%.

U.S. President Donald Trump on Monday shrugged off the possibility that peace talks with Iran could fall apart, telling CNBC, “I don’t care if they’re over, honestly.”

“I really don’t care. I couldn’t care less,” Trump told CNBC’s Eamon Javers in a phone interview midday Monday, adding that he felt the drawn-out negotiations had “started to get very boring.”

Trump was responding to a question about reports earlier Monday that Iranian negotiators were considering ending discussions with Washington and moving to “completely block” the Strait of Hormuz in response to Israel’s military campaign in Lebanon targeting the Iran-backed Hezbollah group.

When asked whether Iranian officials had informed him that they would no longer continue negotiations, Trump replied, “No, they haven’t.”

S&P 500 futures slipped 0.2%, while Nasdaq 100 futures shed 0.3%. Futures tied to the Dow Jones Industrial Average fell by 122 points, or 0.2%.

Overnight on Wall Street, the S&P 500 rose even as oil prices advanced, with Nvidia leading technology higher following the launch of a new chip for PCs.

The broad market index advanced 0.26% to close at 7,599.96, while the Nasdaq Composite gained 0.42% to close at 27,086.81. The Dow Jones Industrial Average added 46.42 points, or 0.09%, and ended at 51,078.88. All three indexes reached new all-time intraday highs and closed at records.
