HONG KONG (Nikkei Markets) -- Hong Kong shares headed lower on Friday as investors remained cautious over Sino-American trade relations and political unrest in the city.
The Hang Seng Index was down 0.5% to 27,153.63 by noon. Pan-Asia insurer AIA Group declined 1.2%, while internet services company Tencent Holdings shed 0.7% and London-headquartered lender HSBC Holdings slipped 0.5%. The three stocks contributed to about half the gauge's losses by points.
Investors this week remained focused on Sino-American trade relations as the date for a possible meeting between U.S. President Donald Trump and Chinese President Xi Jinping at a Group of 20 summit in Japan nears.

Turnover on the main board was at 36.4 billion Hong Kong dollars ($4.65 billion) by noon on Friday, also lower than usual.
