Burma
over half of Burma's population consists of diverse ethnic
groups with substantial numbers of kin beyond its borders; 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; ethnic Karens
flee into Thailand to escape fighting between Karen rebels and
Burmese troops, in 2004 Thailand sheltered about 118,000 Burmese
refugees; Karens also protest Thai support for a Burmese
hydroelectric dam on the Salween River near the border;
environmentalists in Burma and Thailand continue to voice concern
over China's construction of hydroelectric dams upstream on the
Nujiang/Salween River in Yunnan Province; India seeks cooperation
from Burma to keep Indian Nagaland separatists from hiding in remote
Burmese uplands
Burundi
Tutsi, Hutu, 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 in an effort to gain control over populated and natural
resource areas; government heads pledge to end conflict, but
localized violence continues despite the presence of about 6,000
peacekeepers from the UN Operation in Burundi (ONUB) since 2004;
although some 150,000 Burundian refugees have been repatriated, as
of February 2005, Burundian refugees still reside in camps in
western Tanzania as well as the Democratic Republic of the Congo
Cambodia
Southeast Asian states have enhanced border surveillance to
check the spread of avian flu; Cambodia and Thailand dispute
sections of boundary with missing boundary markers and Thai
encroachments into Cambodian territory; maritime boundary with
Vietnam is hampered by unresolved dispute over offshore islands;
Cambodia accuses Thailand of obstructing access to Preah Vihear
temple ruins awarded to Cambodia by ICJ decision in 1962; in 2004
Cambodian-Laotian and Laotian-Vietnamese boundary commissions
reerect missing markers completing most of their demarcations
Cameroon
ICJ ruled in 2002 on the entire Cameroon-Nigeria land and
maritime boundary but the parties formed a Joint Border Commission,
which continues to meet regularly to resolve differences bilaterally
and have commenced with demarcation in less-contested sections of
the boundary, starting in Lake Chad in the north; implementation of
the ICJ ruling on the Cameroon-Equatorial Guinea-Nigeria maritime
boundary in the Gulf of Guinea is impeded by imprecisely defined
coordinates, the unresolved Bakassi 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, then agreed, but has yet to withdraw its forces
while much of the indigenous population opposes cession; only
Nigeria and Cameroon have heeded the Lake Chad Commission's
admonition to ratify the delimitation treaty which also includes
Chad and Niger
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; working toward greater
cooperation with US in monitoring people and commodities crossing
the border; uncontested sovereignty dispute with Denmark over Hans
Island in the Kennedy Channel between Ellesmere Island and Greenland
Cape Verde
none
Cayman Islands
none
Central African Republic
about 30,000 refugees fleeing the 2002
civil conflict in the CAR still reside in southern Chad; periodic
skirmishes over water and grazing rights among related pastoral
populations along the border with southern Sudan persist
Chad
since 2003, Janjawid armed militia and Sudanese military have
driven about 200,000 Darfur region refugees into eastern Chad; Chad
remains an important mediator in the Sudanese civil conflict;
Chadian Aozou rebels reside in southern Libya; only Nigeria and
Cameroon have heeded the Lake Chad Commission's admonition to ratify
the delimitation treaty which also includes Chad and Niger
Chile
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 to
Bolivian gas and other commodities; Peru proposes changing its
latitudinal maritime boundary with Chile to an equidistance line
with a southwestern axis; territorial claim in Antarctica (Chilean
Antarctic Territory) partially overlaps Argentine and British claims
