HONG KONG (Nikkei Markets) -- Hong Kong shares fell by the biggest magnitude in more than a week on Tuesday, weighed down by losses among technology stocks that had been posting gains recently.
The Hang Seng Index shed 1.2% at 31,152.03, marking its steepest decline since May 4. Tencent Holdings, the most valuable company listed in Hong Kong, fell 3.4% from a one-month high ahead of its quarterly earnings report on Wednesday.

Uncertainty over U.S.-China trade relations continued to weigh on investor confidence. While President Donald Trump has said that the U.S. was working well with China on trade matters, some participants were skeptical that contentious trade terms between the two nations could be resolved soon.
"The U.S.-China trade war concerns seem to have eased a bit, but the bilateral trade friction would be a long-term tug of war," said Kenny Wen, wealth management strategist at Everbright Sun Hung Kai. "Even if the ZTE matter is settled, the U.S. will come up with other new issues."
Trump tweeted on Sunday that he was working with his Chinese counterpart Xi Jinping to give telecommunications-equipment maker ZTE a "way to get back into business, fast." The U.S. Department of Commerce last month banned American companies from selling to ZTE.
Trading in ZTE shares remains halted in Hong Kong as well as Shenzhen.
