An Iranian foreign ministry official said good achievements have been made in fixing the Caspian Sea borders as well as outlining the legal regime of the sea.
Deputy Foreign Minister for Asia-Pacific Affaris Ebrahim Rahimpour made the remarks in the 40th meeting of the special working group of the Caspian Sea on June 1, Iran's official IRNA news agency reported.
He said the meeting begins at a time when there is fair ground for further convergence among the littoral countries despite ups and downs in the past years.
All these efforts, he went on to note, culminated in the 4th summit of the Caspian Sea littoral countries where three important documents on the cooperation in living water resources, meteorology and preventing unpredicted disasters were signed.
The agreements certainly paved the way for removing many of the existing problems in the Caspian Sea and gave rise to hopes for settling the remaining issues in near future.
The 40th meeting of the special working group of the Caspian Sea opened June 1 in Tehran, with deputy foreign ministers of the five Caspian Sea littoral states in attendance.
At the working group session on the convention on the legal status of the Caspian Sea, the deputy foreign ministers of Azerbaijan, Iran, Russia, Turkmenistan and Kazakhstan will discuss the articles of a draft of the Sea's legal regime.
The meetings are held periodically in the capital cities of the five littoral states. Baku, capital of Azerbaijan Republic, hosted the previous session.
The Caspian Sea is the largest enclosed water body on earth by area, variously classed as the world's largest lake or a full-fledged sea.
The Caspian Sea Convention will determine the territorial rights of littoral states as well as other matters related to the world's largest landlocked body of water.
