"This applies to diplomatic, official or service, and ordinary passport holders."

Gigaba said the relevant individuals would receive a long-term visa allowing them multiple entry into the country for the duration of the passport's validity, not exceeding 10 years.

The department would continue to meet a turnaround time of five days for short-term business visas.

"Business people from Brazil, Russia, India, and China want to come to our country, buy and sell an increasing array of products and services, and invest in our companies and growth sectors," he said.

"At home affairs we are completely committed to enabling this by facilitating the efficient entry of these commercial visitors, and will continually look for opportunities to improve in this regard."

Gigaba smiled when asked if his announcement would anger countries that had a long-established trading relationship with South Africa.

"No, every good thing must start somewhere," he said.

The same arrangement might well be extended to other countries who had "significant investments" locally.

"These are issues that you undertake as you improve your systems."
