Disputes - international:
Tanzania still hosts more than a half-million refugees, more than any other African country, mainly from Burundi and the Democratic Republic of the Congo, despite the international community's efforts at repatriation; disputes with Malawi over the boundary in Lake Nyasa (Lake Malawi) and the meandering Songwe River remain dormant
Refugees and internally displaced persons:
refugees (country of origin): 352,640 (Burundi); 127,973 (Democratic Republic of the Congo) (2007)
Trafficking in persons:
current situation: Tanzania is a source, transit, and destination country for men, women, and children who are subjected to forced labor and sex trafficking; the incidence of internal trafficking is higher than that of transnational trafficking; girls from rural areas are taken to urban centers and Zanzibar for domestic service; some domestic workers fleeing abusive employers fall prey to sex trafficking; boys are subjected primarily to forced labor on farms, but also in mines, in the informal sector, and possibly on small fishing boats; smaller numbers of Tanzanian children and adults are subjected to conditions of forced domestic service and sex trafficking in surrounding countries, South Africa, Saudi Arabia, the United Kingdom, France, and possibly other European countries; trafficking victims, primarily children from neighboring countries such as Burundi and Kenya, are sometimes forced to work in Tanzania's agricultural, mining, and domestic service sectors; some also are forced into prostitution in brothels
tier rating: Tier 2 Watch List - the government made limited progress towards implementation of its Anti-Trafficking in Persons Act, in part due to poor inter-ministerial coordination and lack of understanding of what constitutes human trafficking; most government officials remain unfamiliar with the Act's provisions or their responsibility to address trafficking under it; however, the government did convict three trafficking offenders (2011)
Illicit drugs:
targeted by traffickers moving hashish, Afghan heroin, and South American cocaine transported down the East African coastline, through airports, or overland through Central Africa; Zanzibar likely used by traffickers for drug smuggling; traffickers in the past have recruited Tanzanian couriers to move drugs through Iran into East Asia.
