"We can't rest, because we are in a competitive world," the Johannesburg-based Sita said.
Earlier this week, South Africa's Industrial Development Corporation said South Africa's performance has global implications.
"It has now fallen on the emerging and other developing economies to sustain the world's growth momentum, since a contraction is forecast in the eurozone, while the USA and Japan are expected to record only modest growth," Jorge Maia, head of research for the corporation, said in a statement accompanying a report focusing on South Africa's key mining sector.
Maia, saying South Africa was lagging behind other countries in getting minerals out of the ground, called for "significantly higher levels of investment, supported by major improvements in the energy and transportation infrastructure."
