Sino-British Joint Liaison Group

Sino-British Joint Liaison Group (Chinese: 中英聯合聯絡小組) or simply Joint Liaison Group was a meeting group formed in 1985 between the Governments of the United Kingdom of Great Britain and Northern Ireland and the People's Republic of China after signing of Sino–British Joint Declaration (Joint Declaration for short), a treaty for the transfer of sovereignty of Hong Kong from Britain to China. It was set up for liaison, consultation and the exchange of information to implement the Joint Declaration and make the transfer of Hong Kong Government in 1997 smooth.

The purpose of the Joint Liaison Group was to: (a) conduct consultations on the implementation of the Joint Declaration; (b) discuss matters relating to the smooth transfer of government in 1997; (c) exchange information and conduct consultations on such subjects as may be agreed by the two sides.

The Joint Liaison Group was specifically tasked with: (1) the action to be taken by the two Governments to enable the Hong Kong Special Administrative Region to maintain its economic relations as a separate customs territory, and in particular to ensure the maintenance of Hong Kong's participation in the General Agreement on Tariffs and Trade (now the World Trade Organisation), the Multi Fibre Arrangement and other international arrangements; (2) the action to be taken by the two Governments to ensure the continued application of international rights and obligations of Hong Kong; (3) the procedures to be adopted for the smooth transition in 1997; (4) the action to assist the Hong Kong Special Administrative Region to maintain and develop economic and cultural relations and conclude agreements on these matters with states, regions and relevant international organisations.

The JLG ceased operations in 1999, two years after the transfer of sovereignty.

Proceedings of the group were generally not public, and details will only become known as they are declassified, from 2015 on, under Britain's 30-year secrecy rule for such official documents.
