Transnational_issues of Angola
| Disputes - international: | many Cabindan separatists have returned to the province from exile since the 2006 ceasefire and peace agreement; concerns from international experts and local populations over the Okavango Delta ecology in Botswana and human displacement scuttled Namibian plans to construct a hydroelectric dam at Popavalle (Popa Falls) along the Angola-Namibia border |
| Refugees and internally displaced persons: | refugees (country of origin): 13,464 (Democratic Republic of Congo) IDPs: 61,700 (27-year civil war ending in 2002; 4 million IDPs already have returned) (2006) |
| Illicit drugs: | used as a transshipment point for cocaine destined for Western Europe and other African states, particularly South Africa |
