Hong Kong May Be Considering Emergency Measures to EndUnrest Joyce Huang The Hong Kong government is probably considering measures to strengthen its crackdown on anti-government protesters after Chinese President Xi Jinping issued a direct warning, urging the city to "end violence and restore order," analysts say. Stepping up the suppression, however, may backfire, fueling tensions in the city and further hurting its economy if protesters refuse to back down, they add. Xi told a summit in Brazil Thursday that "persistent radical and violent crimes have seriously trampled on the basic principle of 'one country, two systems' scheme" in Hong Kong, the state news agency People's Daily reported. Xi's warning "Stopping the violence and restoring order is Hong Kong's most urgent task at present," he said. Xi also expressed support for the city's chief executive, Carrie Lam, the Hong Kong police, and its judiciary in punishing what he called "violent criminals." "The Chinese government is unwavering in safeguarding its sovereignty, security and developmental interests, implementing the 'one country, two systems' scheme and deterring any interference by foreign forces in Hong Kong affairs," he added. While a reiteration of Beijing's long-held stance, Xi's remarks are effectively a direct order for Lam to get tough and end the city's five months of political unrest, said Sang Pu, a critic and Hong Kong commentator. "This [stance] was reiterated by Xi Jinping in his statement in Brazil and this Brazil statement makes sure that suppression overrides and prevails everything else. And this suppression will not go away very easily," Sang said. On Friday, protesters continued to paralyze parts of Hong Kong for a fifth day, forcing schools to close and blocking some main roads, as university students barricaded campuses and authorities struggled to calm the violence. Lam also condemned an "attack" in London on Hong Kong Secretary for Justice Teresa Cheng during a confrontation with protesters, during which Cheng suffered "serious bodily harm," according to Hong Kong government statement. Lam said the incident was barbaric and violated the principles of a civilized society, the Hong Kong government said. .
