AMP will wind up its $434 million ASX-listed China Growth Fund after 54 per cent of eligible unitholders sided with hedge fund Lim Advisors' resolution to close the fund.

The outcome, which was flagged on Wednesday by AMP whose Life unit was prevented from voting on the resolution by a court decision, brings an end to a bitter contest between one of Australia's largest wealth managers and a group of activist investors led by Lim.
