Canada on Friday suspended its extradition treaty with Hong Kong to protest the tough new national security law China has enacted in the financial hub. Canada is also halting exports of sensitive military gear to Hong Kong and updating its travel advisory for the city so Canadians will know how the law might affect them, the foreign ministry said. The Chinese legislation enacted this week outlaws acts of subversion, secession, terrorism and colluding with foreign forces. Beijing has faced a groundswell of criticism, primarily from Western nations, over the law, which radically increases China's control over Hong Kong. China's leaders say the suite of powers will restore stability after a year of sometimes violent protests and will not stifle freedoms. But police have already begun arresting people for possessing protest flags and banners, and the government in Hong Kong has made clear certain political views, especially calls for independence, are now outlawed.
