Senegal
The Gambia and Guinea-Bissau attempt to stem separatist
violence, cross border raids, and arms smuggling into their
countries from Senegal's Casamance region, and in 2006, respectively
accepted 6,000 and 10,000 Casamance residents fleeing the conflict;
2,500 Guinea-Bissau residents fled into Senegal in 2006 to escape
armed confrontations along the border

Serbia
Serbia with several other states protest the U.S. and other
states' recognition of Kosovo's declaring itself as a sovereign and
independent state in February 2008; ethnic Serbian municipalities
along Kosovo's northern border challenge final status of
Kosovo-Serbia boundary; several thousand NATO-led KFOR peacekeepers
under UNMIK authority continue to keep the peace within Kosovo
between the ethnic Albanian majority and the Serb minority in
Kosovo; Serbia delimited about half of the boundary with Bosnia and
Herzegovina, but sections along the Drina River remain in dispute

Seychelles
together with Mauritius, Seychelles claims the Chagos
Archipelago (UK-administered British Indian Ocean Territory)

Sierra Leone
as domestic fighting among disparate ethnic groups,
rebel groups, warlords, and youth gangs in Cote d'Ivoire, Guinea,
Liberia, and Sierra Leone gradually abate, the number of refugees in
border areas has begun to slowly dwindle; UN Mission in Sierra Leone
(UNAMSIL) has maintained over 4,000 peacekeepers in Sierra Leone
since 1999; Sierra Leone considers excessive Guinea's definition of
the flood plain limits to define the left bank boundary of the
Makona and Moa rivers and protests Guinea's continued occupation of
these lands including the hamlet of Yenga occupied since 1998

Singapore
disputes persist with Malaysia over deliveries of fresh
water to Singapore, Singapore's extensive land reclamation works,
bridge construction, and maritime boundaries in the Johor and
Singapore Straits; in November 2007, the ICJ will hold public
hearings as a consequence of the Memorials and Countermemorials
filed by the parties in 2003 and 2005 over sovereignty of Pedra
Branca Island/Pulau Batu Puteh, Middle Rocks and South Ledge;
Indonesia and Singapore continue to work on finalization of their
1973 maritime boundary agreement by defining unresolved areas north
of Indonesia's Batam Island; piracy remains a problem in the Malacca
Strait

Slovakia
bilateral government, legal, technical and economic working
group negotiations continued in 2006 between Slovakia and Hungary
over Hungary's completion of its portion of the Gabcikovo-Nagymaros
hydroelectric dam project along the Danube; as a member state that
forms part of the EU's external border, Slovakia has implemented the
strict Schengen border rules

Slovenia
the Croatia-Slovenia land and maritime boundary agreement,
which would have ceded most of Piran Bay and maritime access to
Slovenia and several villages to Croatia, remains unratified and in
dispute; Slovenia also protests Croatia's 2003 claim to an exclusive
economic zone in the Adriatic; as a member state that forms part of
the EU's external border, Slovenia has implemented the strict
Schengen border rules to curb illegal migration and commerce through
southeastern Europe while encouraging close cross-border ties with
Croatia

Solomon Islands
since 2003, the Regional Assistance Mission to the
Solomon Islands (RAMSI), consisting of police, military, and
civilian advisors drawn from 15 countries, has assisted in
reestablishing and maintaining civil and political order while
reinforcing regional stability and security

Somalia
Ethiopian forces invaded southern Somalia and routed
Islamist Courts from Mogadishu in January 2007; "Somaliland"
secessionists provide port facilities in Berbera to landlocked
Ethiopia and have established commercial ties with other regional
states; "Puntland" and "Somaliland" "governments" seek international
support in their secessionist aspirations and overlapping border
claims; the undemarcated former British administrative line has
little meaning as a political separation to rival clans within
Ethiopia's Ogaden and southern Somalia's Oromo region; Kenya works
hard to prevent the clan and militia fighting in Somalia from
spreading south across the border, which has long been open to
nomadic pastoralists

South Africa
South Africa has placed military along the border to
apprehend the thousands of Zimbabweans fleeing economic dysfunction
and political persecution; as of January 2007, South Africa also

(6,500), and other states in Africa (26,000); managed dispute with
Namibia over the location of the boundary in the Orange River; in
2006, Swazi king advocates resort to ICJ to claim parts of
Mpumalanga and KwaZulu-Natal from South Africa
