British Indian Ocean Territory Mauritius and Seychelles claim the Chagos Archipelago and its former inhabitants, who reside chiefly in Mauritius, but in 2001 were granted UK citizenship and the right to repatriation since eviction in 1965; 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 restricted access to the largest island in the chain

British Virgin Islands
none

Brunei
in 2003 Brunei and Malaysia ceased gas and oil exploration in
their offshore and deepwater seabeds until negotiations progress to
an agreement over allocation of disputed areas; Malaysia's land
boundary with Brunei around Limbang is in dispute; Brunei
established an exclusive economic fishing zone encompassing Louisa
Reef in southern Spratly Islands in 1984 but makes no public
territorial claim to the offshore reefs; the 2002 "Declaration on
the Conduct of Parties in the South China Sea" has eased tensions in
the Spratly Islands but falls short of a legally binding "code of
conduct" desired by several of the disputants

Bulgaria
none

Burkina Faso
two villages are in dispute along the border with
Benin; Benin accuses Burkina Faso of moving boundary pillars;
Burkina Faso border regions have become a staging area for Liberia
and Cote d'Ivoire rebels and an asylum for refugees caught in
regional fighting; the Ivoirian Government accuses Burkina Faso of
supporting Ivoirian rebels

Burma
despite continuing border committee talks, significant
differences remain with Thailand over boundary alignment and the
handling of ethnic rebels, refugees, and illegal cross-border
activities; groups in Burma and Thailand express concern over
China's construction of 13 hydroelectric dams on the Salween River
in Yunnan Province; India seeks cooperation from Burma to keep out
Indian Nagaland insurgents

Burundi
Tutsi, Hutu, and other conflicting ethnic groups, associated
political rebels, armed gangs, and various government forces
continue fighting in the Great Lakes region, transcending the
boundaries of Burundi, Democratic Republic of the Congo, Rwanda, and
Uganda to gain control over populated and natural resource areas;
government heads pledge to end conflict, but localized violence
continues despite UN peacekeeping efforts

Cambodia
land boundary disputes persist among Cambodian claims that
Thailand and Vietnam moved or destroyed boundary markers; maritime
boundary with Vietnam is hampered by dispute over offshore islands;
Cambodia periodically accuses Thailand of obstructing access to
Preah Vihear temple ruins awarded to Cambodia by ICJ decision in
1962; 2003 anti-Thai riots in Phnom Penh resulted in the destruction
of the Thai Embassy, damage to 17 Thai-owned businesses, and
disputes over full payment of compensation

Cameroon
ICJ ruled in 2002 on the entire Cameroon-Nigeria land and
maritime boundary but the parties formed a Joint Border Commission
to resolve differences bilaterally and have commenced with
demarcation in less-contested sections of the boundary, starting in
Lake Chad in the north; the ICF ruled on an equidistance settlement
of Cameroon-Equatorial Guinea-Nigeria maritime boundary in the Gulf
of Guinea, however, implementation of the decision is delayed due to
imprecisely defined coordinates, the unresolved Bakasi allocation,
and a sovereignty dispute between Equatorial Guinea and Cameroon
over an island at the mouth of the Ntem River; Nigeria initially
rejected cession of the Bakasi Peninsula; Lake Chad Commission
continues to urge signatories Cameroon, Chad, Niger, and Nigeria to
ratify delimitation treaty over the lake region, which remains the
site of armed clashes among local populations and militias

Canada
managed maritime boundary disputes with the US at Dixon
Entrance, Beaufort Sea, Strait of Juan de Fuca, and around the
disputed Machias Seal Island and North Rock; uncontested dispute
with Denmark over Hans Island sovereignty in the Kennedy Channel
between Ellesmere Island and Greenland
