Japan should be more aware of the vulnerability of supply of rare metals, especially cobalt from southern Africa. The production of Zaire and Zambia amounts to 74% of cobalt and 8% of copper of the world's production. However, since 1982 its production has been declining. Zaire and Zambia urge to help for improvement of mining and transport facilities. Zambia is dependent upon road and rail way systems link to ports in neighbouring countries for imports and exports. This report describes the current situation of transportation and mining in the area of the Copperbelt.
