Trafficking in persons:
current situation: South Sudan is a source and destination country for men, women, and children subjected to forced labor and sex trafficking; South Sudanese women and girls, particularly those who are internally displaced, orphaned, or from rural areas, are vulnerable to forced labor and sexual exploitation, often in urban centers; the rising number of street children and child laborers are also exploited for forced labor and prostitution; women and girls from Uganda, Kenya, Ethiopia, Eritrea, and the Democratic Republic of the Congo are trafficked to South Sudan with promises of legitimate jobs and are forced into the sex trade; inter-ethnic abductions continue between some communities in South Sudan, with abductees subsequently faced with domestic servitude, forced herding, or sex trafficking; government security forces and armed militia groups continue to recruit children
tier rating: Tier 2 Watch List - South Sudan does not fully comply with the minimum standards for the elimination of trafficking; however, it is making significant efforts to do so; the government has a written plan that, if implemented, would constitute a significant effort toward meeting the minimum standards for eliminating human trafficking; implementation of a UN-backed action plan to eliminate the use of child soldiers in the country’s armed forces continued in 2013, but no officers complicit in the ongoing recruitment of children were investigated, prosecuted, or punished; efforts to address other forms of human trafficking were negligible; South Sudanese law does not prohibit all forms of human trafficking, and authorities did not investigate or prosecute any offenders; limited protection was provided to former child soldiers in 2013, while no steps were taken to identify victims of sex or labor trafficking or to refer them to care (2014)
