China's benchmark indexes delivered mixed performance after a week of trading, amid lingering Middle East tensions.
The Hang Seng Index advanced more than 1%, and the mainland-focused CSI 300 Index edged up a fraction.
After a week of choppy trading, the Hang Seng index decreased 1.3%, and the CSI 300 Index edged up 0.9%.
The Hang Seng Index fell 3.1% in May, while the mainland-focused index rose 2.2%.
China's stocks are attracting investor attention from around the world, participating in a market rally driven by electric vehicle makers, semiconductor chip developers, AI technology and product makers, renewable energy-focused companies, and rare earth and precious metals miners.
Despite the recent run-up in China-based stocks, investors have been cautious about increasing exposure to Chinese companies amid low margins, intense competition, and poor visibility of future profits.
