American Dairy has appointed Zhang Guilang to the position of head of sales and marketing, with immediate effect.

Zhang will replace Nie Bo, who left the Chinese infant formula and milk powder manufacturer to "pursue other interests".

The company said that Zhang joined the company in May as special assistant to the CEO. He has more than 15 years experience in various sales and marketing roles, including general manager of Want-Want China.

"His rich experience with multinational companies and profound understanding of the Chinese dairy market will enable us to further build on our strong foundation with improved international 'best practices' and compete more effectively with foreign competitors on a larger scale than ever before," CEO Leng You-Bin said.
