Boston-based storage and information management services provider Iron Mountain Inc. acquired the Chinese operations of GRM Document Management in a move that will gain it access to more than 2.5 million cubic feet of new storage space.

The New York-listed real estate investment trust will grow its presence in Beijing, Shanghai, Guangdong, Qingdao, Dalian, Chengdu and Wuhan with the purchase of GRM China.

A division of GRM Document, GRM China was the first licensed provider of records and information management services in the country.
