Monday’s reaction was the first since US President Donald Trump kicked off his worldwide tariff war against America’s trading partners. The US slapped a 34 per cent tariff on Chinese imports – including those from Hong Kong – on top of levies that were already in place since Trump’s first trade war in 2018.
Markets on the mainland and in Hong Kong were closed Friday to mark the Ching Ming Festival public holiday.
