Earlier on Monday, Freeport-McMoRan chief executive Richard Adkerson said the company may commence arbitration if it and the government cannot negotiate within 120 days a dispute over its mining contract in Indonesia.

"If there's no agreement, this can be brought to arbitration. Not only Freeport, the government also has a right to bring this to arbitration," Jonan told reporters.
