Under pressure, South Africa is in talks with Namibia, Botswana, Zimbabwe and many others seeking support to fix its porous borders.

South Africa is currently battling illegal migration and an influx of illicit drugs owing to its porous borders.

Addressing an Inter-Ministerial Committee meeting in Johannesburg, the South African Minister in the Presidency, Khumbudzo Ntshavheni, said most of the illegal immigrants are using neighbouring countries as transit routes.

Ntshavheni said the neighbouring countries are being approached because they play a significant role in assisting South Africa to address the longstanding migration challenges while reinforcing infrastructure, technology and management capabilities.

"Illegal immigration is wrong and must be prevented. We are rebuilding and strengthening effective management of migration into South Africa. We have also said, 'Now part of the problem is that we do not have the borderline.' We have gone to Cabinet to seek approval to fund the rebuilding of the borderline so that we can protect the territorial integrity of South Africa."

A couple of weeks ago, Namibia and South Africa concluded a 25-day joint surveillance operation against illegal, unreported and unregulated fishing along the shared marine environment and resources.
