Rounds of talks between Indonesian government officials and the country's coal mining sector over the weekend failed to lift the ban on coal exports that was implemented on 1 January.

Indonesia's government is hoping to reach a decision on resuming coal shipments "in the coming days", its energy minister said on Monday.

"In the past week we have done stocktaking and we hope in coming days there will be more clarity so we can have coal security and resume exports," Reuters quoted energy minister Arifin Tasrif as saying during a meeting with Japan's industry minister, Koichi Hagiuda.
