During a visit in South Sudan in February 2017, Moroccan king Mohammed VI intended to demonstrate how the Algeria-South Africa block feeding secessionist movements in Africa, including the Polisario Front, had failed.[9] In May 2017, South Africa blocked a $5 million shipment of 50,000 tons of Moroccan phosphate heading to New Zealand, on the premise that the phosphorus had been extracted in the Western Sahara region, a situation that is deemed as prohibited only by the Polisario Front.[10]
