Police in Beijing have launched a systematic collection of information on residents in the capital's foreign diplomatic compounds ahead of the 60th anniversary of the founding of the People's Republic. Officers were seen knocking on doors in the Qijiayuan Diplomatic Compound yesterday, asking residents to register their personal details. Emily Chan Miu-ling, a Beijing correspondent with RTHK, said three uniformed officers arrived at her home office in the compound at about 10am. 'They said they were here for resident registration and wanted to get into my apartment, but I refused,' she said. In the end, one officer remained at the RTHK office door and recorded her home return permit and journalist's licence numbers. Chan said the officers visited other apartments in the building. Diplomatic compounds in Beijing used to be the only places foreign media outlets could set up their offices. Many moved out as the rules changed, but some remain in the compounds, which also house foreigners who are not necessarily diplomats. Beijing has put in place far-reaching security measures stricter than those used for last year's Olympic Games in preparation for the 60th anniversary.
