Safeguarding national security – our collective responsibility


National security concerns the welfare of 1.4 billion population of China and the Central People’s Government bears fundamental responsibilities in safeguarding national security. “National security” means a status in which the sovereignty, unity, territorial integrity, sustainable economic and social development, and other major interests of the state are relatively not faced with any danger and not threatened internally or externally, and the capability to maintain a sustained security status.


The Central National Security Commission emphasises the adherence to the “holistic view of national security”, the important areas of which include political security, homeland security, military security, economic security, cultural security, social security, technological security, cyber security, ecological security, resource security, nuclear security, overseas interests security, biosecurity, and security in new domains (space security, deep sea security, polar security).


The Hong Kong Special Administrative Region (HKSAR) is an inalienable part of the People’s Republic of China. The HKSAR has the constitutional duty to safeguard national sovereignty, security and development interests. Every Hong Kong resident should abide by the Basic Law and the laws of Hong Kong, and act in accordance with the law.


Our responsibility to act in accordance with the law

The National People’s Congress adopted the “Decision of the National People’s Congress on Establishing and Improving the Legal System and Enforcement Mechanisms for the Hong Kong Special Administrative Region to Safeguard National Security” at the Third Session of the Thirteenth National People’s Congress on 28 May 2020. The Standing Committee of the National People’s Congress passed on 30 June 2020 the Law of the People’s Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region (the Hong Kong National Security Law) and listed the Hong Kong National Security Law in Annex III to the Basic Law after consulting the Committee for the Basic Law and the HKSAR Government in accordance with the procedures under Article 18 of the Basic Law. The Hong Kong Special Administrative Region Government promulgated the Hong Kong National Security Law for implementation on the same day and the Hong Kong National Security Law took effect at 11pm on that day.

Brief descriptions of the relevant duties of each disciplined force is set out below. Moreover, under the coordination of the Security Bureau, officers from the disciplined forces also serve as “Special Constables”, striving to protect public safety, handle emergencies, etc. Such arrangement helps enhance the manpower and strength of the Hong Kong Police Force.
