Caspian Sea nations sign landmark deal

The leaders of the five states bordering the resource-rich Caspian Sea signed a landmark deal on its legal status on Sunday in the Kazakh city of Aktau, easing regional tensions and potentially facilitating lucrative oil and gas projects.

The leaders of Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan signed the agreement on the status of the inland sea, which has been disputed since the collapse of the Soviet Union rendered obsolete agreements between Tehran and Moscow.

The host, Kazakh President Nursultan Nazarbayev, said before the signing that the leaders were "participants in a historic event."

"We can admit that consensus on the status of the sea was hard to reach and not immediate, the talks lasted more than 20 years and called for a lot of joint efforts from the parties," Nazarbayev said.

Russian leader Vladimir Putin, whose country was seen as driving the deal, said the convention had "epoch-making significance" and called for more military cooperation between the countries on the Caspian.

'Once a frontier oil province'

Sunday's summit is the fifth of its kind since 2002 but there have been more than 50 lower-level meetings since the Soviet breakup spawned four new countries on the shores of the Caspian.

The deal settles a long-lasting dispute on whether the Caspian is a sea or a lake – which means it falls under different international laws.

The draft agreement, briefly made public on a Russian government portal in June, refers to the Caspian as a sea but the provisions give it "a special legal status", Russian deputy foreign minister Grigory Karasin told Kommersant daily.

It is the Caspian's vast hydrocarbon reserves – estimated at around 50 billion barrels of oil and just under 8.4 trillion cubic metres (300 trillion cubic feet) of natural gas in proved and probable reserves – that have made a deal both vital and complex to achieve.

"Disputes arose when the Caspian was a frontier oil province," said John Roberts, a non-resident senior fellow at Atlantic Council's Eurasia Center, while it is "now well established, with major fields approaching peak... production."

'Expand cooperation'

Any deal will "expand the field for multilateral cooperation" between the five states, said Ilham Shaban, who heads the Caspian Barrel thinktank.

But some are likely to view it as more of a breakthrough than others.

Energy-rich but isolated Turkmenistan is particularly excited and President Gurganguly Berdymukahmedov has called for annual Caspian Sea Day celebrations from Sunday onwards.

Turkmenistan could benefit from a concession allowing the construction of underwater pipelines, which were previously blocked by the other states.

Nevertheless, analysts caution that Turkmenistan's long-held plan to send gas through a trans-Caspian pipeline to markets in Europe via Azerbaijan is not necessarily closer to becoming reality.

The plan was previously opposed by Russia and Iran, which could still attempt to block the pipeline – valued at up to $5 billion – on environmental grounds.

"A deal in Aktau is not a legal prerequisite for the construction of the Trans-Caspian Pipeline," said Kate Mallinson, Associate Fellow for the Russia and Eurasia Programme at Chatham House.

"Neither will a major transport corridor to export Turkmen gas to Europe emerge overnight."

Kudos and caviar

As previous exclusive arbiters of Caspian agreements, Russia and Iran could be seen as the new deal's biggest losers.

But while Moscow has ceded ground on underwater pipelines "it gains political kudos for breaking a log-jam," enhancing its image as diplomatic dealmaker, said Roberts of the Eurasia Center.

Russia will welcome the clause barring third countries from having military bases on the Caspian, underscoring its military dominance there, said Shaban of Caspian Barrel.

Iran gets the smallest share of the Caspian spoils under the new deal, but could take advantage of new legal clarity to engage in joint hydrocarbons ventures with Azerbaijan.

In the past Tehran has resorted to hostile naval manoeuvres to defend its claims to contested territory.

Beyond military and economic questions, the agreement also offers hope for the Caspian's ecological diversity.

Reportedly depleted stocks of the beluga sturgeon, whose eggs are prized globally as caviar, may now grow thanks to "a clear common regime for the waters of the Central Caspian," Roberts said.

The deal could result "not only in stricter quotas for sturgeon fishing, but in stricter enforcement of these quotas," he added.
