OTTAWA (Reuters) - Canada is ‘disturbed’ by charges brought against 47 Hong Kong democrats and activists for conspiracy to commit subversion, Foreign Minister Marc Garneau said on Monday, after a crackdown on the democratic opposition under a China-imposed national security law. “Canada is disturbed by the charges laid against 47 individuals for participating in primary elections in #HongKong,” Garneau said on Twitter. “We call on authorities to uphold rights and freedoms, in line with China’s international obligations under the China-Great Britain Joint Declaration.”
