egularly 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 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 Bakassi Peninsula, then agreed,
but 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 the Chad-Niger
and Niger-Nigeria boundaries

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 the expulsions of residents from Darfur in 2003 by
Janjawid armed militia and Sudanese military, about 200,000 refugees
remain in eastern Chad; Chad remains an important mediator in the
Sudanese civil conflict, reducing tensions with Sudan arising from
cross-border banditry; 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 the Chad-Niger and Niger-Nigeria boundaries

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 Briti
