Hong Kong stocks tumbled on Friday after the Chinese government said it planned to impose national security legislation on the city, in the latest sign of how simmering geopolitical tensions have become a significant concern for investors. The city’s Hang Seng index fell 5.6 per cent due to rising fears that the show of legal force could reignite mass pro-democracy protests in the Asian financial hub and worsen tensions between Washington and Beijing. China’s CSI 300 of Shanghai- and Shenzhen-listed stocks fell by 2.3 per cent.
