PERTH, May 23 (Reuters) - Australian diversified miner South32 is open to buying Anglo American's's share of two manganese operations the companies jointly own, should they come for sale at the right price, CEO Graham Kerr said on Thursday.

Anglo is the subject of a takeover offer by the world's biggest listed miner BHP Group, which had previously owned those assets but spun them out with its 2015 demerger of South32.

When asked if South32 would be interested in Anglo's share of its manganese business, Kerr said, "At the right price, absolutely. We know them better than anyone else." He declined to elaborate on what that price might be. (Reporting by Melanie Burton; Editing by Christian Schmollinger)
