HONG KONG (Nikkei Markets) -- Hong Kong shares skidded with the rest of the region on Wednesday after the U.S. said it would impose tariffs on more Chinese goods, potentially escalating a trade war between the world's two largest economies.
The Hang Seng Index had fallen 1.4% to 28,269.72 by noon. Social media and gaming major Tencent Holdings declined 1.8% while China Construction Bank lost 2.2% and London-headquartered HSBC Holdings shed 1.2%. The three contributed most to the index's losses by points.
In the mainland, the Shanghai Composite slumped 1.9% on Wednesday while the onshore traded yuan slid 0.5% against the U.S. dollar to 6.6648.
The Nikkei Asia300 Index fell 1.1%, while futures pointed to a weaker opening for all three major indexes on Wall Street. The White House late on Tuesday said it would assess a 10% tariff on $200 billion of Chinese imports. The news came less than a week after Washington introduced new tariffs on $34 billion of Chinese goods, prompting an equal response from Beijing.
"The risk of a trade war is on the rise again," said Jason Chan, vice head of research at Bright Smart Securities. "From a technical point of view, the Hang Seng Index's recent rebound was accompanied by a relatively small turnover, meaning it had insufficient momentum to rise further."
Chan was referring to the gauge's 1.8% advance across Friday and Monday after the first batch of import tariffs came into effect. He expects the Hang Seng to test support near 28,000 points in the near term.
CSPC Pharmaceutical Group edged 1.1% higher after saying the U.S. Food & Drug Administration had approved its investigational new drug application for the treatment of allergic rhinitis and asthma.
