China has passed a controversial national security legislation for Hong Kong that will cover acts of ‘secession, subversion, terrorism and interference by foreign powers in the territory's internal affairs’ while allowing mainland China’s intelligence agencies to establish themselves there. Critics say this will outlaw dissent and destroy the autonomy and freedoms promised in the Sino-GB agreement when Hong Kong was returned to China in 1997. The draft of the law was announced on the anniversary of this event, symbolically implying that China is in charge and its leaders will do whatever they deem necessary to protect Hong Kong. On 1 July police fired water cannon and tear gas while arresting 300+ people protesting in defiance of the sweeping legislation, and a ‘dissident’ was arrested at the airport before boarding a plane to the UK. Amnesty International warned, ‘China's aim is to govern Hong Kong through fear from this point forward’.
