The annual management charge on Anthony Bolton's Fidelity China Special Situations investment trust will be cut from 1.5% to 1.2% from 1 April 2013.
The move comes as other investment trust providers, including Baillie Gifford, also cut charges to ensure the vehicles remain competitive against open-ended peers post-RDR.
John Owen, chairman of Fidelity China Special Situations, said: "Both the board and Fidelity believe that this competitive pricing will be attractive to new investors considering Fidelity China Special Situations and this will be to the benefit of investors in the company overall."
Bolton had a well-publicised period of poor performance after launching the trust in April 2010, but this has now started to turn around in recent months. The trust's NAV is up 10.1% over the last year, according to FE.
Bolton recently told Investment Week the Chinese equity market looks well supported after an underwhelming 2012 for markets including the Shanghai Composite index.
"Throughout 2012, the Chinese government loosened policy and that is usually a good environment for growth," he said.
"Hong Kong shares turned first last year, and then the A-share market turned, and so far this year January has been positive."
Bolton remains focused on the longer-term potential of consumer-facing stocks in China, with the majority of his portfolio invested in the consumption services theme.
In the later part of last year, the trust's focus on small-and mid-cap stocks started to reap rewards.
