CHIEF Secretary for Administration Anson Chan Fang On-sang has admitted she has little idea about the operations of the PLA and the Ministry of State Security (MSS) in Hong Kong, according to the head of a US inquiry into alleged Chinese espionage. Congressman Christopher Cox said that after a meeting in Washington last month: 'Anson Chan told me she was unaware of MSS activity in Hong Kong - understandable, since the MSS does not report to her - and that she was unaware of the details of PLA activity in Hong Kong, and asked that the US bring this to her attention'. 'I told her the testimony before our select committee was that Hong Kong has a first-class export control system, but that is useless against both Ministry of State Security and PLA operations inside Hong Kong; and further that PLA border crossing are not routinely submitted to Hong Kong Customs inspections.' Mrs Chan denied allegations Hong Kong had been used by the PLA Garrison as a transshipment centre for strategic goods. She invited Mr Cox to visit Hong Kong and to provide further evidence of the alleged illegal diversion of sensitive technology. Last week the Government claimed Mr Cox had changed his view that the SAR was being used as a transshipment centre for strategic goods. But Mr Cox, who published a report in April critical of Hong Kong's role as a transshipment centre, denied he had changed his view. Mr Cox said he would visit the territory if appropriate. The Government yesterday declined to comment on the quotes. A spokeswoman said Mrs Chan made it clear to the Congressman in the meeting that only three central Government organs operated in Hong Kong. They were the Office of the Commissioner of the Ministry of Foreign Affairs, the Hong Kong Garrison of the People's Liberation Army and Xinhua news agency (Hong Kong Branch). 'The Ministry of State Security is not one of them,' the spokeswoman said. 'Mrs Chan also stressed that according to Article 14 of the Basic Law, the Garrison shall abide by the laws of the HKSAR. All military personnel and vehicles are subject to Customs checks. 'She told Mr Cox that the HKSAR operated an autonomous and stringent system of control over strategic commodities, which followed the highest standard practised by the international non-proliferation regimes,' the spokeswoman added. 'We enforce the laws vigorously and strictly.' Democratic Party legislator Cheung Man-kwong said yesterday it was natural that the Government knew little about PLA activity in the territory as the Basic Law stated the central Government was responsible for local military affairs. 'She was just being frank . . . in stating the reality,' he said.
