Sentiment improved slightly after the Hang Seng Index tumbled nearly 2 per cent on Wednesday despite stronger-than-expected economic data from China in the first quarter, before US President Donald Trump imposed tariffs on China. Trump said China could face tariffs of up to 245 per cent because of Beijing’s retaliatory measures.
Trump said on Wednesday that the US and Japan had made “big progress” in talks to hammer out a deal to avoid higher levies.
