Mali provisionally seizes gold mine owned by Canadian company

There's an impasse between the Malian military government and the Canadian gold mining company Barrick Gold. The Malian government wants greater gold revenues and wants to renegotiate contracts, and has gone so far as to arrest, release, then re-arrest Barrick senior employees in Mali. Barrick has not resumed mining operations, and now a court in Mali has provisionally taken oversight of the operations. The World's Host Marco Werman talks with Aanu Adeoye, a correspondent for the Financial Times, about the roots of the disagreement and how it escalated.
