In a blog for the London Review of Books, RVI Fellow Jérôme Tubiana describes a year of research in Sudan and South Sudan on arms flows in Sudan. ‘Tracing their origin,’ he writes, ‘might make it easier to put pressure on the states and companies delivering arms to the warring parties, often in violation of (theoretically) tough international laws.’ With his collaborator, Claudio Gramizzi, Tubiana identifies Iranian anti-personnel landmines, S8 rockets from Belarus, Russian cluster munitions, as well as Weishi WS-1 rockets, anti-tank mines, and Kalashnikov ammunition, all provided to the Government of Sudan by its biggest supplier, China.
