March 2005, the national oil companies of China, the Philippines,
and Vietnam signed a joint accord to conduct marine seismic
activities in the Spratly Islands; Philippines retains a dormant
claim to Malaysia's Sabah State in northern Borneo based on the
Sultanate of Sulu's granting the Philippines Government power of

the Amur and Ussuri confluence and in the Argun River in accordance
with the 2004 Agreement, ending their centuries-long border
disputes; the sovereignty dispute over the islands of Etorofu,
Kunashiri, Shikotan, and the Habomai group, known in Japan as the

occupied by the Soviet Union in 1945, now administered by Russia,
and claimed by Japan, remains the primary sticking point to signing
a peace treaty formally ending World War II hostilities; Russia and

with the land and maritime treaty ratified by Russia in May 2003 and
by Lithuania in 1999; Lithuania operates a simplified transit regime
for Russian nationals traveling from the Kaliningrad coastal exclave
into Russia, while still conforming, as an EU member state with an
EU external border, where strict Schengen border rules apply;
preparations for the demarcation delimitation of land boundary with
Ukraine have commenced; the dispute over the boundary between Russia
and Ukraine through the Kerch Strait and Sea of Azov remains
unresolved despite a December 2003 framework agreement and on-going
expert-level discussions; Kazakhstan and Russia boundary
delimitation was ratified on November 2005 and field demarcation
