After a 19 per cent rally on the Hang Seng Index from an April low, investors are worried that the run-up was too fast. While China and the US agreed to cut tariffs on each other’s imported products, the tentative deal is in place for 90 days, with some economists warning that the issues between the two nations remain protracted. Investors will focused more on economic challenges, such as China’s deflationary trend and sticky inflation in the US.
Other major Asian markets mostly edged lower. Japan’s Nikkei 225 slid 1.1 per cent, while South Korea’s Kospi retreated 0.2 per cent and Australia’s S&P/ASX 200 was little changed.
