Sinkmaster and hitlery did this for a political (obviously) reason. It was because the second largest deposit of hard coal was in Indonesia, and he promised to close off the Escalante area to leave Indonesia the virtual sole producer. I’ve been to Escalante area.

IIRC it is an extremely high grade of coal, clean burning and low sulphur Riady seems to have chosen Clinton back in the 80's for future high office.
Just search Clinton Riady for articles on scandals involving the two. Riady pleaded guilty in 2001 to conspiracy to defraud the United States through illegal contributions to Clinton's campaigns. He was barred from entry into the USA but, in 2009, was giving a waiver. mmmm
