The Hong Kong Government could lose its last links with London following a Trade and Industry Bureau review which may see its office move to Berlin.
Many of the office's former roles had been taken over by the Chinese Embassy and its future was in question, said outgoing director-general of the Hong Kong Economic and Trade Office in London John Tsang Chun-wah.
The bureau was re-examining how it distributed its resources and might decide to close its offices in the British capital now Britain was not so important to the SAR, Mr Tsang said.
'My office is now looking at the whole issue of Europe and how to deal with it. London is still one of the world's biggest financial centres but clearly we now need to look at Berlin or somewhere else in Europe as a base,' he said.
Before the handover the London office had a staff of more than 120 with responsibility for liaising with the former sovereign power and taking care of Hong Kong migrants.
But many of these roles have since been taken over by the Chinese Embassy and the London office's staff has been reduced to about 20 dealing solely with trade issues.
