Johannesburg (AFP) - When
South Africa's President Jacob Zuma visited Nigeria last week he was on
a delicate mission to mend rifts between the continent's two economic
powerhouses.
The election of Nigeria's President Muhammadu Buhari into office last May did not immediately ease the tension.
When Zuma visited Abuja last week, Buhari set aside diplomacy and accused one of South Africa's largest companies of failing the country in its fight against the Boko Haram insurgency.
Telecoms
giant MTN was fined $3.9 billion for missing a deadline to disconnect
5.1 million unregistered SIM cards, a legal requirement aimed at
hampering the militant Islamists.
Buhari
said MTN was "very slow" in cutting off the lines and that the
unregistered lines were used by "terrorists" and "contributed to the
casualties".
The Nigerian government's concern "was basically on the security, not the fine imposed on the MTN," he said.
But MTN is not the only South African company riding rough waves in Nigeria.
Hotel
and resort chain group Sun International is also a target of
investigation by the country's economic financial crimes commission.
"We
have an exemplary track record of operating in many countries over the
past 30 years, but the difficulties we have experienced in Nigeria are
unprecedented," Michael Farr, Sun International group's general manager
for communications, told AFP.
