Belize
Guatemalan squatters continue to settle in the largely
uninhabited rain forests of Belize's border region; OAS seeks to
revive the 2002 failed Belize-Guatemala Differendum that created a
small adjustment to land boundary, a Guatemalan maritime corridor in
Caribbean, joint ecological park for disputed Sapodilla Cays, and
substantial US-UK financial package
Benin
Benin and Burkina Faso military clash in 2006 over sections of
riverine boundary involving disputed villages and squatters; much of
Benin-Niger boundary, including tripoint with Nigeria, remains
undemarcated; in 2005, Nigeria ceded thirteen villages to Benin as a
consequence of a 2004 joint task force to resolve maritime and land
boundary disputes, but clashes among rival gangs along the border
persist; a joint boundary commission continues to resurvey the
boundary with Togo to verify Benin's claim that Togo moved boundary
stones
Bermuda
none
Bhutan
approximately 105,000 Bhutanese have lived decades as
refugees in Nepal, 90% of whom reside in seven UN Office of the High
Commissioner for Refugees camps; Bhutan cooperates with India to
expel Indian separatists
Bolivia
Chile rebuffs Bolivia's reactivated claim to restore the
Atacama corridor, ceded to Chile in 1884, offering instead
unrestricted but not sovereign maritime access through Chile for
Bolivian natural gas and other commodities
Bosnia and Herzegovina
Bosnia and Herzegovina and Serbia and
Montenegro have delimited most of their boundary, but sections along
the Drina River remain in dispute; discussions continue with Croatia
on several small disputed sections of the boundary related to
maritime access that hinder ratification of the 1999 border agreement
Botswana
commission established with Namibia has yet to resolve
small residual disputes along the Caprivi Strip, including the
Situngu marshlands along the Linyanti River; downstream Botswana
residents protest Namibia's planned construction of the Okavango
hydroelectric dam at Popavalle (Popa Falls); Botswana has built
electric fences to stem the thousands of Zimbabweans who flee to
find work and escape political persecution; Namibia has long
supported and in 2004 Zimbabwe dropped objections to plans between
Botswana and Zambia to build a bridge over the Zambezi River,
thereby de facto recognizing their short, but not clearly delimited
Botswana-Zambia boundary
Bouvet Island
none
Brazil
unruly region at convergence of Argentina-Brazil-Paraguay
borders is locus of money laundering, smuggling, arms and illegal
narcotics trafficking, and fundraising for extremist organizations;
uncontested dispute with Uruguay over certain islands in the
Quarai/Cuareim and Invernada boundary streams and the resulting
tripoint with Argentina; in 2004 Brazil submitted its claims to the
United Nations Convention on the Law of the Sea (UNCLOS) to extend
its maritime continental margin
British Indian Ocean Territory
Mauritius and Seychelles claim the
Chagos Archipelago including Diego Garcia; in 2001 the former
inhabitants of the Chagos Archipelago, evicted in 1965 and now
residing chiefly in Mauritius, were granted UK citizenship and the
right to repatriation; the UK resists the Chagossians' demand for an
immediate return to the islands; repatriation is complicated by the
exclusive US military lease of Diego Garcia that restricts access to
the largest island in the chain;
