HONG KONG (Nikkei Markets) -- Hong Kong shares completed their third weekly decline on Friday, as uncertainty over Sino-American trade relations turned investors cautious.
The Hang Seng Index rose 0.3% to 27,353.93 on Friday, but fell 2.1% for the week. Heavyweight Tencent Holdings shed 8.7% during the week, extending losses after it reported first-quarter results earlier this month. It was the stock's worst weekly performance since November.
Sunny Optical Technology Group slumped 11.3% over the past five days, leading percentage declines on the gauge for a second consecutive week after its customer Huawei Technologies was added to a list of entities that would need U.S. government approval to buy components and technology from American companies. AAC Technologies Holdings, which also supplies parts to Huawei, dropped 2.4% during the week.
In Friday's trading, Tencent and Sunny Optical lost 0.4% each, while AAC Technologies rose 1.8%.
The U.S. move on Huawei came shortly after Washington raised tariffs on $200 billion-worth of Chinese goods and Beijing announced a planned retaliation. U.S. President Donald Trump on Thursday said Huawei could be included in a trade deal between the two countries.
The last round of trade talks between the world's largest economies took place earlier this month, with Trump and Chinese President Xi Jinping scheduled to meet at a G-20 summit in Japan in June.
"This conflict is unlikely to be resolved in the near-term, so the rebound should be short-lived," said Linus Yip, chief strategist at First Shanghai Securities. "If there is no progress in trade talks, market sentiment will still tend to be cautious. The Hang Seng Index will have a downward bias in the short term."
