Hong Kong metro system carries about 5 million passengers a day The increasingly violent protests have roiled the former British colony for four months HONG KONG: Hong Kong police fired tear gas on Sunday as protesters defied an emergency law and marched wearing masks through the Chinese-controlled city, witnesses said. There was no obvious reason for the tear gas, as the rally at Pacific Place on Hong Kong island seemed peaceful, said one witness. Tens of thousands of protesters wore face masks in defiance of colonial-era emergency powers that threaten them with a year in prison for hiding their faces. Hong Kong’s rail operator reopened part of its metro system on Sunday after an unprecedented shutdown, but kept many typically busy stations closed, as the Chinese-ruled city braced for large demonstrations expected later in the day. Meanwhile, a Hong Kong court rejected a challenge to the emergency law criminalizing protesters wearing face masks. Pro-democracy lawmakers went to the High Court on Sunday seeking an emergency injunction against the ban, arguing the emergency powers bypassed the legislature and contravened the city’s mini-constitution. But a senior judge dismissed their injunction demand. Violent protests had erupted across the Asian financial center soon after Lam wielded the colonial-era powers for the first time in more than 50 years to order the ban in hopes of curbing months of unrest. The night’s “extreme violence” justified the use of the emergency law, Beijing-backed Lam said on Saturday, when the city felt eerily quiet, with the subway and most shopping malls closed and many roads deserted. Despite the closure of the metro, which carries about 5 million passengers a day, hundreds of anti-government protesters took to the streets, defying the ban on face masks, but had largely dispersed by evening. Hong Kong’s protests have plunged the city into its biggest political crisis in decades, posing the biggest popular challenge to Chinese President Xi Jinping since he came to power. “These extreme radicals have rampant arrogance and behave vilely,” China’s representative Liaison Office in Hong Kong said on Sunday, denouncing Friday’s destruction of one of its buildings by “extremist militants.” “We strongly condemn this and support the SAR government and the police to severely punish illegal violent elements in accordance with the law,” it said in a statement, referring to Hong Kong’s status as a special autonomous region of China. Rail operator MTR Corp. said it would not open some stations on Sunday, as it needed time to repair vandalized facilities, and also cut short operations by more than three hours, to end at 9 p.m. Most supermarkets and commercial stores reopened after the previous day’s closures, although some malls, such as Sogo in the bustling Causeway Bay commercial district and IFC in Central, remained shuttered. Global luxury brands from Prada to Cartier are counting the costs as the unrest has kept tourists away, taking retail sales down 23 percent in August, their biggest decline on record. Many restaurants and small businesses have had to shut repeatedly, with the protests pushing Hong Kong’s economy to the brink of its first recession in a decade. The increasingly violent protests that have roiled the former British colony for four months began in opposition to a bill that would have allowed extradition to mainland China, but have spiraled into a broader pro-democracy movement. Lam said the ban on face masks, which many protesters use to conceal their identities, was ordered under the emergency laws that allow authorities to “make any regulations whatsoever” in whatever they deem to be in the public interest. But it enraged protesters, who took to the streets on Friday to vent their anger, many of them masked in open defiance. Some set fires, hurled petrol bombs at police and burned the Chinese national flag, in a direct challenge to authorities in Beijing. The current “precarious situation,” which endangered public safety, left no timely solution but the anti-mask law, Matthew Cheung, Hong Kong’s chief secretary, wrote on his blog on Sunday. He urged people to oppose violence ahead of grassroots district council elections set for Nov. 24. Financial Secretary Paul Chan also addressed the protests in his blog, saying that despite recent obstacles, Hong Kong’s banking system remained sound and the financial market was functioning well. Protesters have taken aim at some of China’s largest banks, trashing ATM machines at branches of Bank of China’s Hong Kong unit, for example, while nearby international counterparts, such as Standard Chartered, have escaped untouched. Chan’s comment came after Hong Kong’s Monetary Authority said about 5 percent of the city’s ATMs could not transact cash withdrawals for ‘various reasons.’ The Hong Kong Association of Banks (HKAB) condemned violent acts “which have caused serious damage to some bank branches and ATMs.” Protesters are angry at what they see as creeping interference in Hong Kong, which Britain returned to China in 1997 under a “one country, two systems” formula guaranteeing freedoms that are not enjoyed on the mainland. China dismisses the accusation, saying foreign governments, including Britain and the United States, have fanned anti-China sentiment.
