The public relations firm that rebranded Hong Kong as 'Asia's world city' and designed its fiery dragon symbol two years ago has been asked by the government to help restore the city's image and regain investor confidence as moves begin to look beyond the Sars crisis. Burson-Marsteller will be paid $1.3 million for the project. Speaking after the first meeting of the Economic Relaunch Strategy Group yesterday, Financial Secretary Antony Leung Kam-chung said : 'This PR firm has a lot of experience in crisis management around the world and we hope that the communication can be improved.' But Mr Leung also warned that premature market revival measures would not benefit the economy. Crisis management was essential first, followed by a strengthening of public confidence domestically and internationally, then active promotion of Hong Kong. Secretary for Commerce, Industry and Technology Henry Tang Ying-yen yesterday hit out at event organisers Reed Exhibitions after it banned 71 Hong Kong traders from joining the world's biggest jewellery fair in Las Vegas at the end of this month over fears of Sars infections. 'The action is unnecessary and unreasonable because the World Health Organisation is satisfied that we have not exported any Sars patients recently and we are getting fewer and fewer infections,' he said. Hong Kong's economic and trade office in London had asked Reed Exhibitions' head office in the UK to lift the ban, he said.
