05:48 AM EST, 01/07/2025 (MT Newswires) -- Asian stock markets were uneven on Tuesday, with most trading floors closing in the green, but China-exposed exchanges falling back on possible international-commerce tensions.

Hong Kong and Shanghai finished down, while Tokyo green and most other regional markets closed higher.

In Japan, the Nikkei 225 opened higher and rose to the close, finishing up 2% as traders embraced tech issues after overnight gains of peer issues in New York. Shipping line shares fell back.

The benchmark Nikkei 225 rose 776.25 to 40,083.30, as gaining issues outnumbered losers 141 to 80.

Leading the upside was chip-making equipment manufacturer Tokyo Electron, up 11.2%, while video-game maker Nexon declined 2.9%.

In Hong Kong, the Hang Seng Index opened lower and slipped in trading, finishing off 1.2% on reports of possibly additional China-US trade hurdles pending in Washington.

The broad gauge Hang Seng fell 240.71 to 19,447.58, as losing issues outnumbered gainers 48 to 31. The Hang Seng TECH Index lost 0.9% on the day, while the Mainland Properties Index was steady.

Leading the upside was Semiconductor Manufacturing International, gaining 5.1%, while internet-colossus Tencent declined 7.3%.

China-based Tencent and battery-maker CATL were among "Chinese military companies operating in the US" published recently in the US Federal Register, a definition that could restrict US commerce with the companies in the future. Tencent and CATL said their inclusion was a mistake and misunderstanding, reported the South China Morning Post.

On the mainland, the Shanghai Composite rose 0.7% to 3,229.64.

On the other regional exchanges, the S. Korean KOSPI rose 0.1%; the Taiwan TWSE inclined 0.4%; the Australian ASX 200 inclined 0.3%; the Singapore Straits Times Index rose 0.3%, and the Thai Set inclined 1.3%. In late trading in Mumbai, the Sensex was up 0.2%.
