TOKYO -- Shares retreated Wednesday and Hong Kong's Hang Seng index dipped nearly 2% as thousands continued protests against proposed legislation that many city residents fear could further erode the territory's legal autonomy.
The Hang Seng lost 1.9% to 27,264.54 as thousands of protesters, most of them youths, prevented lawmakers from entering Hong Kong's government headquarters Wednesday.
The demonstrations snarled traffic and delayed a legislative debate on a bill that would allow criminal suspects in Hong Kong to be sent for trial in mainland China, a proposal that is sharpening fears over growing Chinese control and an erosion of civil liberties in the semiautonomous territory.
The crowds overflowed onto a major downtown road as they overturned barriers and tussled with police, who used multiple rounds of tear gas and threatened to use more forceful measures if necessary.
The proposed legal changes have spooked investors, Stephen Innes of SPI-Asset Management said in a commentary, as it "could have far-reaching consequences for attracting overseas talent and does question the viability of Hong Kong as a leading financial hub, which of course is spooking property investors."
Japan's Nikkei 225 index lost 0.4% to 21,129.72 and the Kospi in Seoul shed 0.1% to 2,108.75. The Shanghai Composite index declined 0.6% to 2,909.38. Australia's S&P ASX 200 edged less than 0.1% lower to 6,543.70. Shares rose in Taiwan but fell in Jakarta and Thailand.
On Wall Street, defense contractors suffered steep declines and technology stocks gave up most of their early gains, taking the steam out of a morning rally.
The market had advanced for five straight days since the Federal Reserve signaled it is open to cutting interest rates if needed to stabilize an economy rattled by trade disputes. The gains had erased much of the S&P 500's 6.6% decline in May. But Tuesday, concerns that the U.S. trade spat with China could be prolonged and hurt growth in the world's two biggest economies dimmed investor enthusiasm.
President Donald Trump told reporters Tuesday he expects to meet with Chinese leader Xi Jinping in Osaka at the summit of the Group of 20 major economies. But he said he's prepared to expand 25% tariffs already imposed on $250 billion of Chinese exports to cover another $300 billion if a deal with Beijing falls through.
"It's me, right now, that's holding up the deal," Trump said in comments carried by CNBC and other news outlets. "And we're either going to do a great deal with China or we're not doing a deal at all."
The yield on the 10-year Treasury has dropped from around 2.50% in early May to 2.13% Wednesday.
