Dentsu Aegis Network has appointed Motohiro Yamagishi as CEO Dentsu Aegis Network China, with Phil Teeman appointed group managing director.
KF Lee will remain chairwoman and Nubuaki Kyushima chief operating officer.
Commenting on the appointment, Teeman said the opportunity to work with a best-in-class management team to drive the integration of the company and grow the business is immense.
"I look forward to seeing Dentsu Aegis Network China flourish under the new management.”
In support of the new management structure, Dentsu Aegis Network will co-locate all of its businesses in Shanghai into one premises in the Xintiandi area.
It marks its biggest co-location so far with over 1,400 staff moving into one building, following the official establishment of Dentsu Aegis Network in January 2014.
Tadashi Ishii, president and CEO of Dentsu, added: “China has always been one of the most important overseas markets to us, and its successful integration is key to our overall strategic layout and development.
"I am looking forward to seeing the new management team drive more growth in China. The Shanghai office co-location enables us to provide better integrated service to our clients.”
