Britain and China have been urged to explain how they see the future of the Joint Liaison Group in the wake of the row over its post-handover role. The Legislative Council's constitutional affairs panel decided yesterday to ask both sides to disclose documents and minutes of talks on the JLG's post-handover role between the two sides before the signing of the Joint Declaration in 1984. The Joint Declaration says the JLG will continue its work until January 1, 2000. Acting Secretary for Constitutional Affairs Clement Mak Ching-hung noted legislators' concerns and promised to relay the message to both parties. At the centre of the controversy is Annex II of the Sino-British Joint Declaration, which stipulates that the Joint Liaison Group is to conduct consultations on the implementation of the Joint Declaration. Cheung Man-kwong of the Democratic Party said: 'Does that mean that the JLG would just have a cup of tea and a bun? Or that they would have to review whether China or Britain breached the Joint Declaration [after the handover]?' Dr Yeung Sum of the Democratic Party said: 'Our future hinges on the Joint Declaration. Otherwise, what was the point of signing it?' The row developed after premier Li Peng said: 'Someone said they will still monitor the implementation of the Joint Declaration after July 1. This is unrealistic.' The Joint Liaison Group is to begin its plenum in London today.
