Indonesia will allow small businesses to manage mines in the commodities-rich country for the first time and broaden access for religious groups, the latest populist policy to emerge under President Prabowo Subianto in his first months of rule.

Indonesia's parliament is set to vote on Tuesday on a bill to revise the country's mining law to boost development of domestic mineral processing industries and regulate mining permits for religious groups and universities.

The amendment aims to help small companies access mining and ensure ore supply security to develop Indonesia's domestic metals sector.
