May 2020, state media announced that the Standing Committee of the National People's Congress (NPCSC) would begin drafting a new law that covers "secession, foreign interference, terrorism and subversion against the central government", to be added into the Annex III of the Hong Kong Basic Law. This meant that the law would come into effect through promulgation, bypassing local legislation. Despite international pressure, the NPCSC passed the national security law unanimously on 30 June, without informing the public and the local officials of the content of the law. The law created a chilling effect in the city. Demosistō, which had been involved in lobbying for other nations' support, and several pro-independence groups announced that they had decided to disband and cease all operations, fearing that they would be the targets of the new law. Thousands of protesters showed up on 1 July to protest against the newly implemented law. On that day, the police arrested at least ten people for "breaching national security" for displaying protest art. Following the implementation of the national security law, the international community reassessed their policies towards China. Major countries in the West (Canada, the US, the UK, Australia, Germany and New Zealand) suspended its extradition treaty with Hong Kong over the introduction of the national security law. The US Congress passed the Hong Kong Autonomy Act and president Donald Trump signed an Executive Order to revoke the city's special trade status after Mike Pompeo informed the Congress that Hong Kong was no longer autonomous from China and so should be considered the same country in trade and other such matters. On 7 August, the US announced that they would impose sanctions on eleven Hong Kong and Chinese top officials, including Carrie Lam, for undermining Hong Kong's freedom and autonomy. British Home Office announced that starting from early 2021, current and former holders of the BN(O) passport in Hong Kong can resettle in the UK along with their dependents for five years before they become eligible to apply for permanent citizenship.
