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 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 British
claims; action by the joint boundary commission, established by
Chile and Argentina in 2001, for mapping and demarcating the
disputed boundary in the Andean Southern Ice Field (Campo de Hielo
Sur) remains pending

China
in 2005, China and India began drafting principles to resolve
all aspects of their extensive boundary and territorial disputes
together with a security and foreign policy dialogue to consolidate
discussions related to the boundary, regional nuclear proliferation,
and other matters; recent talks and confidence-building measures
have begun to defuse tensions over Kashmir, site of the world's
largest and most militarized territorial dispute with portions under
the de facto administration of China (Aksai Chin), India (Jammu and
Kashmir), and Pakistan (Azad Kashmir and Northern Areas); India does
not recognize Pakistan's ceding historic Kashmir lands to China in
1964; about 90,000 ethnic Tibetan exiles reside primarily in India
as well as Nepal and Bhutan; China asserts sovereignty over the
Spratly Islands together with Malaysia, Philippines, Taiwan,
Vietnam, and possibly Brunei; the 2002 "Declaration on the Conduct
of Parties in the South China Sea" has eased tensions in the
Spratlys but is not the legally binding "code of conduct" sought by
some parties; Vietnam and China continue to expand construction of
facilities in the Spratlys and in March 2005, the national oil
companies of China, the Philippines, and Vietnam signed a joint
accord on marine seismic activities in the Spratly Islands; China
occupies some of the Paracel Islands also claimed by Vietnam and
Taiwan; China and Taiwan have become more vocal in rejecting both
Japan's claims to the uninhabited islands of Senkaku-shoto (Diaoyu
Tai) and Japan's unilaterally declared equidistance line in the East
China Sea, the site of intensive hydrocarbon prospecting; certain
islands in the Yalu and Tumen rivers are in an uncontested dispute
with North Korea and a section of boundary around Mount Paektu is
considered indefinite; China seeks to stem illegal migration of tens
of thousands of North Koreans; China and Russia prepare to demarcate
the boundary agreed to in October 2004 between the long-disputed
islands at the Amur and Ussuri; demarcation of the China-Vietnam
boundary proceeds slowly and although the maritime boundary
delimitation and fisheries agreements were ratified in June 2004,
implementation has been delayed; environmentalists in Burma and
Thailand remain concerned about China's construction of
hydroelectric dams upstream on the Nujiang/Salween River in Yunnan
Province

Colombia
Nicaragua filed a claim against Honduras in 1999 and
against Colombia in 2001 at the ICJ over disputed maritime boundary
involving 50,000 sq km in the Caribbean Sea, including the
Archipelago de San Andres y Providencia and Quita Sueno Bank;
dispute with Venezuela over maritime boundary and Los Monjes Islands
near the Gulf of Venezuela; Colombian-organized illegal narcotics,
guerrilla, and paramilitary activities penetrate all of its
neighbors' borders and have created a serious refugee crisis with
over 300,000 persons having fled the country, mostly into
neighboring states
