Institutional Investor recently conducted its 11th China 20 Money Managers survey, which reveals that the nation's top 20 mutual fund managers now have assets under management exceeding $1 trillion, a milestone for the industry, which began only in 1998 when regulators first began allowing professional investment managers to market their services to the public at large.

Since 2005, II has ranked China's top mutual fund managers by AUM. The rankings are a result of a survey of top funds' assets for the 12 months ending March 31.
