Didia is a town in Liberia on the coast of the Atlantic Ocean. It lies about 30 km to the southeast of the town of Buchanan.
Didia is the proposed site of a new port for the export of iron ore from Simandou and Zogota in Guinea. A standard gauge railway is proposed to connect this port with iron ore mines across the border in Guinea.
The mine, railway and port are being developed by SMFG [1]
