China, HK shares slide as Trump risks and profit-taking fuel tech sell-off

China and Hong Kong stocks declined on Tuesday due to a sell-off in tech heavyweights and increased U.S. tariff risks. The Hang Seng Tech Index dropped 0.03%, with Alibaba and Baidu slipping. The decline follows concerns over new U.S. semiconductor curbs on China and overnight drops in U.S.-listed Chinese stocks. The market consolidation reflects geopolitical and investment policy uncertainties.
