With South Sudan's President Salva Kiir undergoing medical tests abroad after years of rumours about his health, analysts say a long-gestating plan has been set in motion to secure his succession.
Kiir returned from at least 10 days in the United Arab Emirates on Wednesday, with state media saying he had been "exploring new avenues for economic cooperation".
But members of his entourage, speaking on condition of anonymity, previously told AFP he was there for medical tests -- reinforcing long-held concerns about the 73-year-old's health.
The world's youngest country, South Sudan has been plagued by poverty and violence since gaining independence in 2011, including a civil war that killed some 400,000 people in 2013-2018.
