The 12th session of the special working group for the Caspian Sea area at the level of deputy foreign ministers is opening in Tehran on Tuesday.
The participants in the session will discuss the clauses of the Convention on the Caspian Legal Status, with 60% of it already coordinated.
On December 9-10, the sides will consider such problems as sea safety and prevention of the Caspian militarisation by non-littoral states. They will also discuss the use of oil and gas resources of the unique sea-lake, navigation, fishing and ecology.
A joint Tehran statement is expected to sum up the session.
The Russian delegation is headed by deputy foreign minister, special envoy of the Russian president in the Caspian Sea region Viktor Kalyuzhny. He already conducted negotiations with his Iranian counterpart Mehdi Safari on December 8.
The settlement of contentious issues of the Convention on the Caspian Legal Status is the most complicated and acute problem to be discussed by the littoral states.
