SHANGHAI: Hong Kong shares fell on Tuesday, led by technology stocks, as elevated Sino-US tensions dented sentiment.

In China, shares rose as a sustained strength in artificial intelligence-related stocks and state-owned enterprises stocks countered weakness elsewhere.

Hong Kong’s benchmark Hang Seng Index was down 0.7%, and the China Enterprises Index lost 0.9%.

China warned US House Speaker Kevin McCarthy on Tuesday not to “repeat disastrous past mistakes” and meet Taiwan President Tsai Ing-wen, who is visiting the United States.

Meanwhile, US President Joe Biden’s administration said on Monday it could not confirm reports that China was able to collect real-time data from a spy balloon as it flew over sensitive military sites earlier this year, saying analysis was still ongoing.

Tech stocks in Hong Kong slumped 1.6%, with Alibaba and Meituan down 3.0% and 4.4%, respectively.

Shares of Chinese electric-vehicle makers traded in Hong Kong also plunged, following a drop in Tesla shares in the United States. Shares of Nio and XPeng declined 7.6% and 6.5%, respectively.

In China, shares of state-owned enterprises and semiconductor companies lent some support to the market, while new energy-related sectors gave up some of their earlier gains.
