A proposed bill allowing mainland China to pursue government critics and criminals in Hong Kong and extradite them to China drew protest marches by thousands on 9-11 June, causing a debate on 12 June to be cancelled. The Catholic diocese of Hong Kong joined the social welfare sector and the largest teachers’ union in voicing concerns about the bill. Two thousand counsellors, carers, therapists, and religious groups went on strike. A strike organiser said, ‘We are forced to take a stand on this moral question of right and wrong.’ Several other Christian denominations in Hong Kong also voiced concerns. Police fired rubber bullets and tear gas at protesters, who threw bricks and projectiles back. People are worried that the civil rights and freedoms guaranteed to Hong Kong under the ‘one country two systems’ arrangement will be eroded under the new law. China often uses accusations of non-political crimes to prosecute its critics.
