On 13 July 2018 the UN Security Council passed Resolution 2428 on South Sudan. Resolution 2428 imposes an arms embargo on South Sudan by calling upon all UN member states to prevent supply, sale or transfer of arms to South Sudan until 31 May 2019. The embargo also withholds training, technical and financial assistance related to military activities or materials. The resolution also “[emphasizes] that those responsible for violations of international humanitarian law and violations and abuses of human rights must be held accountable,” and that the government of South Sudan “bears the primary responsibility to protect its population from genocide, war crimes, ethnic cleansing, and crimes against humanity.”
