BRITAIN'S intelligence activities in the region look set to be carried out from Australia following the closure of the communications spy base at Chung Hom Kok. But Hong Kong is still likely to be used to help spy on China and nearby nations after 1997. The British Trade Commission is believed to be a part of London's spying network, as are other consulates in the territory. It has long been mooted whether the new British Consulate being built in Central to house the commission after 1997 will take over certain espionage activities Chung Hom Kok used to perform. A building services expert from the Foreign and Commonwealth Office, Robin Philirs, is here to oversee the installation of heating and ventilation equipment - places where sensitive devices are often hidden. Chung Hom Kok on Stanley peninsula was used from the early 1970s to collect information shared by United States, Australia and New Zealand. The station closed this year and the land will revert to the Hong Kong Government. It was believed to have had a role in monitoring troops in the build-up to the Tiananmen Square massacre and gauging China's reaction to the break-up of the Soviet Union.
