The United Nations Panel of Experts on South Sudan in a 2017 report declared: "Reports from independent sources indicate that the border areas between South Sudan and the Sudan and Uganda remain key entry points for arms, with some unsubstantiated reports of smaller numbers of weapons also crossing into South Sudan from the Democratic Republic of the Congo. There are also persistent reports and public accusations of shipments to forces affiliated with the leadership in Juba from further afield, specifically from Egypt". The same report stated that a Ukrainian Air Force IL-76 transport jet flew in two L-39 jets to Uganda on 27 January 2017 in the full knowledge the L-39 jets were intended to go on to South Sudan, thereby violating the arms embargo the Ukraine had placed on arms sales to South Sudan. In 2018, the United Nations Security Council imposed a worldwide arms embargo on South Sudan, but the embargo has been widely ignored where despite a ceasefire signed the same year, both sides have continued to import arms on a massive scale, suggesting that they are preparing for another bout of the civil war.
