Raymond Ma has taken over management of the Fidelity Funds Greater China fund from Joseph Tse, who has left the asset manager.
Fidelity says Tse left following a decision to make changes to his career and lifestyle.
Ma will take on the $406m (£258.7m) Greater China fund. He took over the £5m China Consumer fund in 2011.
The manager joined Fidelity in 2006 as an investment analyst and has more than 12 years experience of researching companies in the Chinese market. He was made director of research in 2010, responsible for the Greater China research team.
