K.N. Tang, AC Nielsen SRG chairman, Asia Pacific, says the move would enable the group to deliver world standard, quality market research within the fast growing market. The trend, he says, is for clients "to have a combined management structure covering China and Hong Kong markets and they want a single point of contact". Louis Tong will become chairman of the new group. Other executives are Andrew Floyd, managing director, media services; Juling Ngai, managing director, retail services; Vivien Pau, managing director customized services; and Simon Yum, China joint venture executive director.
