Foreign mining corporations have been instructed by Guinea’s military junta that they must share revenues equally with the country and meet a May deadline to show plans to build local refineries.

The West African country is the world’s second-largest producer of bauxite, a mineral needed to make aluminium, and it wants to reap greater benefits from the post-mining process of converting the raw material into alumina.

The White House said in a statement on Facebook that a more fair relationship with foreign corporations was a “win-win.”

Guinea’s leader, Mamady Doumbouya, has reportedly stated that if the deadline of the end of May is not met, consequences will be imposed.
