Vanessa Donegan, head of Asian equities at Columbia Threadneedle is set to retire at the end of the year following 32 years at the firm and its predecessors.
Donegan (pictured) will oversee the transitioning of portfolios over the next few months with lead managers formally taking over on 1 October.
Subject to approval, the £612m Threadneedle Asia fund will be co-managed by George Gosden and Soo Nam Ng while the £131m China Opportunities fund will be run by current deputy manager Jin Xiu, who will become lead manager on 1 October.
Having started her career at Grieveson Grant Stockbrokers in 1981, Donegan subsequently joined Allied Dunbar Asset Management in 1986, which merged with Eagle Star to form Threadneedle Asset Management in 1994.
Mark Burgess, CIO, EMEA, at Columbia Threadneedle, said: "Vanessa's contributions both to Columbia Threadneedle and to our industry have been immeasurable and she has been integral to helping build Columbia Threadneedle into the firm it is today.
"She has been an investor through historically transformational times in Asian equity markets and has spearheaded our efforts to build an integrated structure whereby our Asian teams in different geographies collaborate with their investment colleagues across the globe.
"She has also been a role model to women entering the industry and has mentored young female talent through the business.
"While we are sad to see Vanessa go, today's announcement is the result of robust succession planning, and she leaves in place a strong and successful team.
"I am excited about our global Asia equities capabilities under Soo Nam Ng's leadership, continuing to offer clients quality growth and high conviction strategies."
Donegan commented: "I have also seen huge change in the breadth of investment opportunities on offer in Asian markets, particularly in the markets of India and China.
"I am proud of the Asian equities franchise I leave behind and look forward to the team continuing to deliver for our clients under Soo Nam's leadership."
