Togo's vast phosphate resources are mostly exported in their raw form, and Dangote's project would process some of that phosphate to make fertiliser in-country, aiming to export it to the region.

The cost of the project is around $2 billion, a statement from Togo's government said, without specifying how much of that would come from Dangote.

Dangote also signed a deal to build a cement factory at a cost of around $60 million. Construction of the factory is set to start in the first quarter of 2020 and it will begin producing by the end of next year, the statement said.

The cement would serve the Togolese market as well as export to neighbouring countries.

The deal marks Dangote's first push into Togo, setting billionaire Aliko Dangote's firm up for competition against Germany's HeidelbergCement, which operates three companies there, and Fortia Cement.
