The most important international initiative aimed at shedding light on the oil industry’s often murky finances faces a crucial test next month when several African countries may be forced to leave due to their low governance standards.

The decision is expected at a board meeting of the Extractive Industries Transparency Initiative in Accra, Ghana, starting on February 21. Under the EITI, mineral-rich governments should disclose revenues they receive from international oil and gas companies as a step towards curbing malpractice and looting in an industry seen as one of the most corrupt in the world.
