Moss departs Burson-Marsteller China after almost six years, most recently as a director at the firm, which counts Motorola as a client. He remains based in Beijing.
As Imagethief, Moss has built a strong following for a blog which often takes an irreverent look at media, brands and communications in China.
'I'm thrilled to be joining Motorola, especially now,' Moss told PRWeek Global. 'It's a rare opportunity to work for a company with an outstanding pedigree in mobile communication in one of the most exciting regions and during one of the most exciting times the industry has ever seen.'
'I was fortunate to build my career in China with Burson-Marsteller, and I leave with a great deal of respect and affection for the team there.'
