AN EXHIBITION of the winners of a major advertising award is coming to Hong Kong. The One Show Winners' Exhibition will tour Southeast Asia, reaching Hong Kong on September 19 and 20, before moving to Singapore. Mary Warlick, the executive director of The One Club - a New York-based organisation which aims to maintain advertising standards - said English-language advertising produced in Southeast Asia had a worldwide creative reputation. Entries from the region to the awards had doubled. Award co-sponsors are Tien Wah Press, Batey Advertising and Media Magazine of Hong Kong. THE magazine Asia Precious, the monthly business title for Asia's jewellery, gemstone and diamond industries, has appointed Tomko Ltd of Melbourne, as its sales agent. Under the terms of the agreement, Tomko will be exclusively responsible for Asia Precious advertising sales and circulation in Australia, New Zealand and Fiji. DAVID Liu has been named executive director for China Operations for Bozell Hong Kong. He will be responsible for developing, co-ordinating and managing the agency's China business and operation. Before Mr Liu's transfer back to Hong Kong last year as regional account director, he was a director of client services for two years at Bozell Taiwan. ASIA Business News Hong Kong bureau chief Rebecca Lim has resigned to go back to the United States for personal reasons. It is not yet known who will replace Ms Lim, who was with the fledging Singapore-based financial network from its beginning last year.
