SHANGHAI: Ruder Finn has lost its Hong Kong MD Peter Witton, after only a year, to telecoms client Davnet. The agency has responded by poaching Edelman's Shanghai MD of six years, Jean Michel Dumont, to head the agency's Shanghai-based China operations. He takes up the post this month. RF's current China head, Susanna Archibald, will replace Witton in Hong Kong. The agency has offices in Beijing and Shanghai. There are plans for a third Chinese office to open later this year.
