The leaders of Nigeria and South Africa have pledged to take “concrete measures” to stem future outbreaks of xenophobic violence, during a state visit to South Africa by Nigerian President Muhammadu Buhari. “We’ve agreed that we are going to set up mechanisms between our two countries, early warning mechanisms will be set up so that once we see that there is restiveness. We will be able to inform one another to find ways — and active ways — of ensuring that we do not have recurrences. And at the same time, we will cooperate at a number of levels, including the policing level, including the intelligence-sharing information level.” Buhari’s three-day visit will also include a business forum and a meeting of a bi-national commission that seems to boost cooperation between the two countries. He will also meet with Nigerian expatriates in Johannesburg, South Africa’s largest city.
