Former chief secretary Anson Chan Fang On-sang has become an adviser to an investment fund set up by former Hutchison Whampoa taipan Simon Murray. Mrs Chan, whose 16-month pre-retirement leave finished in August, also recently took up the post of a director of the Asia Investment Corporation. She accepted the offer of being a consultative committee member of the Gems Oriental & General Fund. The technology-focused fund was founded by Mr Murray, former managing director of tycoon Li Ka-shing's flagship company Hutchison Whampoa. Its consultative committee includes celebrities such as former US secretary of state Henry Kissinger. The Civil Service Bureau confirmed yesterday Mrs Chan had been given permission to take up the two posts. 'But we do not intend to comment on the details of individual cases because we must respect the privacy of the retired officers concerned,' a bureau spokeswoman said. Retired officials at director of bureau rank or above must seek permission for taking up employment in Hong Kong within three years of retirement. Applications are processed by the bureau with the advice of the Advisory Committee on Post-retirement Employment. 'The key guiding principle for approving an application for post-employment is that the prospective employment should not conflict with public interest or embarrass the government,' the spokeswoman said.
