FAILURE to meet export requirements, declining demand for locally produced goods and interference from the labour movement have forced some companies to withdraw from Namibia’s Walvis Bay Export Processing Zone (EPZ), an economic watch group says. This is taking place barely three years after Namibia’s EPZ plans got off the ground. In its quarterly review made public on Wednesday, the Namibian Economic Policy Research Unit said incentives put in place by government to attract investors in the more labour intensive manufacturing sector have not helped curtail the unemployment situation in the country.
