The South African Minister of Transport, Sindisiwe Chikunga, says Africa's transport sector needs to redouble its intra-trade efforts to optimise the Trans Kalahari Corridor.

She was speaking at the Trans-Kalahari Corridor ministerial council meeting in Windhoek.

Chikunga revealed that trading among African nations stands at less than 16% in comparison with trading between Africa and the European region, which is over 75%.
